Dec. 14, 2011 The results of the final exam, and your final points total and your grade for the class are now posted in the "Your Points" page. Click HERE for the regular onground class, and Click HERE for the online/hybrid class. Remember to hit refresh on any page if something does not look right. Now that the final points have been posted there is no way for you to change them, there is no extra credit, no way of changing any points for any reason. I have personally regraded all of the final exams for all students who were within 20 points of the grade cutoffs. There will be no further regrades. It has not escaped my attention that several of you have points totals that are close to the cutoffs, however, I have already looked at your final exams and there are no more points for you to earn. If this is you, I understand your frustration and you have my sympathy, but please remember that the majority of students who earned the higher grade scored more than 100 points more than you did. Now that the final grades have been posted there is no way for your to change your grade, no extra credit, nothing, please do not ask, thank you! The only exceptions are if there has been a serious data entry error. If you find one then send me an email, although I may not be able to respond for a couple of weeks. Any serious data entry errors can be corrected when I return. I need to leave town early tomorrow and so I will not be available to discuss the test or your performance in class until the start of next semester. I also have a lot of things that I still need to do this evening and so I may not respond to any emails starting immediately, unless there is a real grade emergency. Many of you worked extremely hard in this class, I know that it was also very time consuming, I thank you all, you are one of the best groups I have ever worked with. Please enjoy your break and I look forward to seeing as many of you as possible (even though I don't actually see very many of you) and working with you next semester. And don't forget, as was mentioned repeatedly in class, we have a lot to learn next semester! The results for the final exam were as follows: Onground class: Max possible score incl. 10 extra credit points = 385 Highest score attained = 381 Lowest Score = 31 Mean = 287 Median = 306 St. Dev. = 74 Online/Hybrid class: Max possible score incl. 10 extra credit points = 385 Highest score attained = 376 Lowest Score = 47 Mean = 264 Median = 283 St. Dev. = 85 More... |

Dec. 13, 2011 Grades will be posted LATE (maybe very late) Wednesday evening, sorry! |
|
Dec. 10, 2011 For the final, you are allowed bring any molecular models that you think would be useful, but as before, please don't bring the entire kit (you will spill it and won't have time to build stuff from scratch anyway), just bring a couple of pre-built pieces, e.g. a chiral center or a cyclohexane ring. |

Dec. 10, 2011 Today's review session has been posted. Warning, long file!! More... |

Dec 10, 2011 GRADING THE FINAL: The final exams will be graded as usual and after the points have been totaled, ALL students who are within 20 points of a grade cutoff will have their entire exam regraded by me. After that the points will be final, there will be no further regrades, no extra credit, nothing, please don't ask. If you missed a grade by a couple of points it will not have gone unnoticed by me, I will have already regraded your test, there will be no mechanism for finding even 2 more points, you will have missed the grade, sorry. If you miss a grade by a couple of points please remember that on average most people who got the higher grade had at least 100 points more than you did. There has to be grade cutoffs somewhere you just missed it. As soon as grades are posted I have to leave immediately for the UK for a family issue, and so I will not be around to discuss your performance in the class. You will have to wait until the start of next semester. You will be able to pick up your final exams during any office hours at the beginning of next semester. Sorry to sound so blunt and unsympathetic, but there have to be grade cutoffs somewhere. Entering grades is my least favorite thing to do in teaching. |
|
Dec 10, 2011 EXTRA CREDIT ON THE FINAL: As promised there will be 2 extra credit questions on the final. These will both come from the "O-Chem in Real Life" postings since the 3rd midterm. |
|
Dec 9, 2011 I was asked about what mechanisms you need to know for the final exam. You need to know the alkene mechanisms on the following pages of the Alkenes I notes: page 7 (both), page 8, page 9 (both), page 13, page 14, and also the hydrolysis of the epoxide on page 2 of Alkenes II. This looks like a long list, but many of the steps are repeated among different mechanisms. You also need to know the mechanisms of the SN1/SN2/E1/E2 reactions, but again, the more mechanisms you do the more they start to look the same rather than different. And BOTH the substitution (page 16) and the radical addition (page 15) mechanisms in the Alkenes I notes, but they are very closely related to each other AND(!!), please try the mechanisms in the problem set for closely related reactions, i,e., applying these principles in different contexts. If at all possible you really need to get into the mode of thinking about mechanisms as something that help you understand, rather than something additional you need to know. You may not believe me, but a student in CHM 233 has made a couple of useful videos that will hopefully convince you of the same thing. I think that a student's perspective is very valuable. To see the video of mechanistic principles, click HERE. To see the short video on alkene mechanisms, click HERE. |

Dec. 7, 2011 Today's review session has been posted. We did not cover as much material as I had intended, although we did a lot of work on important fundamental stuff like acids/bases bond dissociation energies etc. I had meant to cover cyclohexanes and Newman projections but did not get there. Conformations and cyclohexanes were, however, covered in previous review sessions, for Newman projections, click HERE, and for cyclohexanes, click HERE. Conformations and Cyclohexanes were also reviews for midterm #2, click HERE. I also intended to review nomenclature if I had time, but didn't. I probably will not review nomenclature, you are on your own there! On Saturday we will review Alkene reactions, substitution and elimination and mechanisms. The review session will probably last more than 2 hours! More... |

Dec. 7, 2011 I have made a series of small moves to help with solving R/S absolute configuration problems at chiral/asymmetric centers, with increasing difficulty from 1 to 5. Click HERE for movie #1, click HERE for movie #2, click HERE for movie #3, click HERE for movie #4, and click HERE for movie #5. The last problem starts with a name and generates a structure. |

Dec. 6, 2011 The "Your Points" page has been updated with all quizzes and all midterms after all regrades. Please check to make sure that there are no errors. Any errors must be brought to my attention by 11:59PM Friday Dec. 9th. After that there will be NO FURTHER CHANGES except the addition of your points for the final exam. More... |

Dec. 5, 2011 UPDATE: There will be TWO review sessions for the final. The first will be Reading Day, Dec 7th, at 10AM - Noon in LS A-191. Reading Day is the last day that I can reserve a classroom. So, I can't reserve a room for the second review, on Saturday Dec. 10th. LS A-191 will probably be available, so assemble OUTSIDE, and if it is in use we will have to go and find another classroom. The time for the Saturday review will be 3:30PM as usual. Both reviews will cover different material and both will be recorded as usual. |

Dec. 5, 2011 Today's lecture has been posted, it is the last lecture this semester. The lecture consisted of most of the remaining reactions of alkenes that we were supposed to cover this semester and was a bit hurried, so I apologize for that. There are several new reagents that you need to know from this lecture for the final. Because this material was a bit hurried, and because some of this we will not use much next semester, I will provide a reaction/reagent chart for THE REACTIONS COVERED IN THIS LAST LECTURE ONLY, so that you won't have to memorize these reagents. The important ones of those covered today you will learn next semester anyway because we will use them a lot, so I don't feel TOO guilty about doing this! To see the reaction/reagent chart that you will have on the final exam that you can use to answer questions related to the reactions covered today, click HERE. This summary will be stapled to your final exam. Note that this summary does not explain how any of the reactions proceed and does not contain stereochemical information, its purpose is to avoid you having to memorize a lot of new reagents. You are responsible for understanding the stereochemical consequences of these reactions, understanding how they work in different contexts, and in particular, knowing the mechanism of the conversion of an epoxide into a 1,2-diol in the presence of aqueous acid.

Dec 5, 2011 There is an error in the halides notes. At the top of page 16, the two diastereomers are named (1R)-bromo-(1,2R)-diphenylpropane (on the left) and (1S)-bromo-(1,2R)-diphenylpropane (on the right), however, they should be (1R)-bromo-(1,2R)-diphenylpropane and (1R)-bromo-(1,2S)-diphenylpropane. In other words, the R and S configurations are switched in the right hand structure. Apologies, and thanks to the students who found this typo. |

Dec. 4, 2011 There will be TWO review sessions for the final. The first will be Reading Day, Dec 7th, at 10AM - Noon in LS A-191. Reading Day is the last day that I can reserve a classroom. So, I can't reserve a room for the second review, on Saturday Dec. 10th. LS A-191 will probably be available, so assemble OUTSIDE, and if it is in use we will have to go and find another classroom. The time for the Saturday review will be 3:30PM as usual. Both reviews will cover different material and both will be recorded as usual. |
|
Dec. 4, 2011 The last lecture is tomorrow, Dec. 5th! We will obviously not complete the last section of the notes, AlkenesII. We will only cover "1. Additional Reactions of Alkenes", we will not start part 2. That will complete the material that you will be responsible for for the final exam. The only thing I regret not covering is "2.2 From Alcohols (E1 and E2 elimination in a new context)" (I think that you talked about that one in the lab), but that is where we will start next semester. |

Dec. 3, 2011 There will be a review session/office hours today at 3:30PM IN LS A-191, the subject will be SN1 vs SN2 vs E1 vs E2, predicting mechanisms, products and stereochemical consequences. |
|
Dec. 1, 2011 I have decided that I don't like section 8 of the Halides notes "Summary of Nucleophiles and Bases", I have redone this part and we will use the new version in class tomorrow. To get the gapped version of this section, click HERE (pdf file). I will bring some copies of the gapped version of this section to class tomorrow. |

Nov. 28, 2011 Today's lecture has been posted. Again, the projector in LS A-191 was not working so I had to use the board, the posted lecture was recorded in my office. As usual when this happens, the in-class lecture does not cover as much material as I should because I have to write everything on the board, and so the recorded lecture is only ca. 35 minutes or so. This puts us even slightly further behind than we were! We will not finish the notes this semester, but the part of Alkenes II that we miss is not very important since we revisit it at the start of next semester. However, we will have to hurry a little to cover all of the reactions that we are supposed to this semester, sorry! More... |

Nov 27, 2011 The last Quiz #14 has been posted. The deadline for submission of Quiz #14 is SUNDAY Dec. 4th. Quiz #13 has been graded. For question #10 both C and D were accepted as correct answers. Answer C was supposed to mean two structures that were a pair of enantiomers, but it could have been interpreted as 2 pairs of enantiomers. More... |

Nov 23, 2011 I know that some of you wanted to get an early start on problem set #4, and so the first part (A) has now been been posted. This part focuses on the larger concepts from earlier in the semester and chirality. Some of the alkene reaction problems you will have seen from the 3rd problem set, they are given again here in the context of optical activity and stereochemistry/enantiomers. The questions on page 18 of this problem set are difficult, most are harder than you should expect to see on the final (I meant to put that on the problem set but forgot). The rest of problems set #4 will be posted later in the semester, More... |

Nov. 18, 2011 Today's lecture has now been posted, apologies for the delay. Also posted is the Fischer projection "mini-Lecture" that is mainly for those who may take the MCAT, click HERE. I do not ask questions about Fischer projections on my tests. The lecture uses page 8 of the "Chirality notes". To get to the Fischer projection problems referred to in the mini-Lecture, click HERE. More... |
|
Nov. 18, 2011 There will be a review session tomorrow afternoon at 3:30PM in LS A-191. The topic will be stereochemistry, recognizing enantiomers, determining R/S, with emphasis on the stereochemistry of alkene addition reactions. |
|
Nov. 16, 2011 I managed to salvage today's lecture file intact after all, and the lecture is now posted on the lecture page as usual. Please take note of the announcement at the start of the lecture, we need as many people as possible to participate in our chemical education research study. You will be completely anonymous in this study, we do not look at individual students and if need most of the class to join the study or our statistical analysis will be biased and weak. Thank you! I will record the Fischer Projection "mini-lecture" hopefully tomorrow, Thursday. More... |

Nov. 15, 2011 Asking for your help! One of the things we do in my group is run an ongoing study in chemical education research. We want to understand that factors that contribute to success for students in organic chemistry classes. One of the ways we do this is by looking for correlations of student performance with demographic and other data. We are now asking you to participate in this study. You will do this by completing a survey and giving us permission to use your test scores. Participation is completely voluntary and is completely anonymous. To ensure anonymity, each student is assigned a code number. Only me and my graduate student Hagit Ben-Daat will have access to the password protected computer file that connects the names to the code numbers. The study does not look at or track the performance of individual students, we just look for trends in class performance as a whole. You do not earn any extra credit for participating, you do not lose any credit for not participating. If you agree to participate now you can withdraw at any time without penalty. The next time that you submit a quiz you will be asked if you would like to participate. Obviously we need as many of you as possible to do so since we need the statistics of large numbers on our side if we want to be able to draw any meaningful conclusions! If you have decided not to submit any more quizzes then please use this link (same as at the top of this page) to participate. We thank you in advance for helping our research, we hope that this will help us to improve the teaching of organic chemistry for future classes. |

Nov. 14, 2011 We had technical problems AGAIN today, this time the projector in LS A-191 refused to work. After wasting a lot of time I decided to give the lecture on the white boards, which was less than ideal because today's subject really required the use of molecular models. So, I re-recorded the lecture in my office, WITH the use of the models, and so if you were in class today and you were slightly confused, you can try watching again with the models. The recorded lecture is short because we wasted a lot of time at the beginning with the projector, and also because I had to draw everything on the board in class, which slowed me down. So, this put us even further behind, sigh! This lecture covered how to determine the absolute configuration of asymmetric centers, which requires either the use of models, or some mental agility to reorient the molecule in space. There is an alternate method of determining R/S that uses your hands, which is difficult to illustrate in class, but is shown in a small movie, click HERE. More... |

Nov 4, 2011 My completed version of Section H of the notes, AlkenesI, has now been posted on the Lecture Material page. As usual, please make sure that your notes are complete and have no errors. At the end of these notes is a summary of the reactions that may be useful. The online notes also contain a "test yourself" section that is less useful to you at the moment because we have not yet covered all of the reactions, but still suggests a study strategy. Specifically, you can test yourself on writing the PRODUCTS, click HERE, test yourself on writing the REAGENTS, click HERE, and test yourself on writing the REACTANTS, click HERE.

Nov. 3, 2011 This evening's review session has been posted. At the end of the review session I left you with a problem to solve related to NMR chemical shifts. To the problem, click HERE, to see my answer, click HERE. I also promised to post the spectra for the 2 worked spectrum problems that we covered in the previous two review sessions. I just realized that these two are the same ones that are given as worked examples on the Spectroscopy section of the Problems page. At the start of the "Combined Spectral Problems starting with Molecular Formula" Section there are two worked problems, together with pdf files of the spectra that you can look at or print to follow along with me as I solve the problems, click HERE and look for the small red f Flash symbol. Or you can print them and follow along withe the review session files HERE for the first problem, and HERE for the second problem (start at 53 mins). We will solve at least one more of these at the review session on Saturday. More... |

Nov 3, 2011 UPDATE: There will be TWO pre-test review sessions. The first will be this evening, Thursday 3rd, 6 - 8PM, and will be held in WGHL 101. WGL is apparently Wrigley Hall, where the School of Sustainability is. Sorry, I don't get to choose the locations! This review will take the place of office hours tonight. The second will be Saturday afternoon, 3:30 - 5:30PM, and will take the place of normal office hours/review session that day. The Saturday review will be in PS H-150. Both will be recorded and both will cover different material. |

Nov 2, 2011 So, how do you avoid getting overwhelmed by the new material, specifically the reactions? To see a suggested study strategy, click HERE. This is a Quicktime movie file, and it is a bit big(!). It is also a bit longer than I intended, ca. 20 mins, but I still think that it is worth watching if you are feeling lost. The strategy described here will be useful later this semester, and especially next semester when we do a lot more reactions. |

Nov 2, 2011 Question numbers 7, 8, 9 and 10 from the "Reactions" section "Mechanisms and Energy Diagrams" problems should be ignored, don't worry about these questions. These relate to radical reactions of alkenes that we did not cover before the midterm. I am in the process of moving those problems to the Alkene I Cumulative Problems. More... |
|
Nov 2, 2011 UPDATE: The material for midterm exam #3 will end with Section 4.5, i.e. sections 4.6, 4.7, 4.8, 4.9 will NOT be on the test. Therefore, you should ignore the following problems on the problem set: page 14, problems b, g page 16, problems d, f page 17, problem g page 19, the first mechanism on that page I will be posting some suggested study advice on how to approach the material, specifically the alkenes and their reactions, later this evening. They are not as bad as they look once you understand what you are required to know. |

Oct 30, 2011 Do you what some volunteer experience and a chance to help Dr. Gould and his wife? We run a program called "I'm College Bound", click HERE, the goal of which is to make attending college a realistic goal for all Jr. High kids. The way it works is simply that we take ASU students into the Jr. High science classroom to help with a science lesson. You can't tell them that they should go to college, you can just bring it to their attention by being in the classroom. ASU students are better role models/mentors that my wife or I, the more varied the mentors (i.e. you) the more likely they are to get the attention of the varied kids in the classroom. If you attended Kino Jr. High in Mesa then you would be a particularly valuable mentor, they need to see ex-Kino students in college. We go to Kino, and we also bring Kino students onto the ASU campus for a field trip. Our first visits to Kino this semester will be directly after the next midterm exam, Tuesday November 8th and Wednesday November 9th. The Kino visit to ASU will be Nov. 17th. We will need volunteers for all 3 days. If you can go to Kino you will need to commit to attending one of the class periods. These are as follows: Tuesday 9AM - 10:50AM Tuesday 10:50Am - 12:40PM Tuesday 2PM - 3:50PM Wednesday 9AM - 10:40AM Wednesday 10:40 - 12:20PM Wednesday 12:55 - 2:30PM If you can help with the field trip to ASU you would need to be available for a good chunk of the day, but the schedule is not yet set for the field trip. If you are interested in helping, please send me an email, letting me know which days you might be able to help. If you are unable to help on these days but are interested in helping in the future (we will go again next semester), let me know and I will keep you on the mailing list. Thanks! |

Oct 26, 2011 My completed version of Section G of the notes, Reactions, has now been posted on the Lecture Material page. As usual, please make sure that your notes are complete and have no errors. I changed the notes a little bit compared to your notes, specifically section 4.1, to match better what I said in lecture. The changes are small, I don't think that you need to go back and change your notes to match. I wanted to emphasize that reactions that have negative and positive free energies are exergonic and endergonic, respectively, whereas reactions that have negative and positive reaction enthalpies are exothermic and endothermic, respectively. This wasn't clear in the version of the notes that I prepared at the beginning of the semester that you have. I also added a few sentences at the end that discusses the heuristic and algorithm approaches to solving organic reaction problems that I talked about in class. You do not have to worry about this, I just wanted a complete set of notes, you will not be tested on the difference between heuristics and algorithms :) More... |

Oct. 22, 2011 Today's review session has been posted. At the end of the review session we solved a spectrum problem of the kind that will be on the next test. I couldn't record that part, so I solved it on the board. Therefore, there is a separate small recoding file on the lectures page right under the Review Session file that shows how to solve the problem, so don't forget to look at that one too. More... |

Oct 18, 2011 To solve problem #4 on Quiz #9 you will need to know about how substitution on carbon influences chemical shift in a carbon nmr spectrum, i.e. what would the relative chemical shifts be for a tertiary versus a primary carbon atom. We did not discuss this very much in class, but look at the bottom of page 20 of the spectroscopy notes for help with this. More... |

Oct. 12, 2011 The second midterm is this coming Monday Oct. 17. Students in the Online/Hybrid class MUST take the test in PS H-150. Students in the Regular Onground class must take the test in LS A-191. When you enter the room, DO NOT SIT IN ANY OF THE SEATS IN THE FRONT ROW of either classroom. These seats are reserved for students entering late, so that the rest of the class will not be disturbed by latecomers clambering over the seats. You can use a model kit if you wish, but DO NOT BRING THE ENTIRE MODEL KIT! Just bring a preassembled cyclohexane with a couple of substituents if you need it, or a small pre-assembled butane fragment with a couple of different atoms for substituents that you can use to draw Newman projections etc, again, only if you think it will be helpful to you. The midterm will be mainly on the material covered since the last midterm up to Infrared Spectroscopy, i.e. NOT including NMR spectroscopy. You will not be asked to solve mass spectrometry problems, because it i too easy to make simple arithmetic errors determining molecular formulae from molecular weights etc., however, you should understand the principles of mass spectrometry and be prepared to answer questions that relate to how the method works and do not need any simple math calculations. Note that organic chemistry exams are necessarily cumulative and you will need to be able to draw proper resonance contributors if needed, Lewis structures, recognize cis- trans- isomers etc. Check the Problem Sets page to see what spectral correlation charts you will be provided with on the exam, or just check the cover page of any of the recent old exams.

Oct. 12, 2011 There will be two pretest review sessions for the 2nd midterm exam. The first will be Thursday Oct. 13, 6 - 8PM (this will take the place of normal Thursday evening office hours), the second will be Saturday Oct. 15, 3:30 - 5:30PM (this will take the place of regular Saturday office hours). Each review session will cover different material, both will consist mainly of problem solving, and both will be recorded as usual. I have not been able to reserve a room for the review session on Thursday! So, assemble OUTSIDE PS H-150 (do NOT go inside the classroom just in case it is in use, or is about to be used), and if H-150 is in use we will find one of the other H-wing classrooms to use. On Saturday the review session will be in LS A-191. |

Oct 7, 2011 Tomorrow's office hours (Saturday Oct. 1st, 3:30 - 4:30PM) will be held in LS A-191, NOT H-150 (unless they haven't unlocked it, I do have the room reserved tomorrow). Most of the office hours will consist of a problem-solving review session where we will work practice problems related to cyclohexane conformations. I will be available after the problem session for 1-on-1 questions in LS A-191. The review session will be recorded and posted online just like the lectures. |

Oct. 5, 2011 Alkane conformers is a very visual 3-D topic, that is often best understood using models and small movies. Here are some movies that may help. To see the difference between electron repulsion and steric interactions, click HERE It is important that you understand exactly how to interpret the chair conformation of cyclohexane, and how it relates to the 3D cyclohexane structure. To see a short movie on this click HERE, and for a substituted cyclohexane, click HERE. To see the cyclohexane chair to chair interconversion movie that was shown in class, click HERE Cyclohexane conformations are MUCH more understandable if you build a model. To see how to do this click HERE You need to be able to generate the 2 chair conformations for substituted cyclohexanes, if you are not sure how to do this, click HERE to see how to avoid some common misconceptions. |

Oct. 2, 2011 Occasionally I will make some small changes to the problems that are included as part of the notes. Obviously I can't do this on the printed version that you have, but I can change the electronic versions that are on the website on the "Problems" page. I do this if there are errors in a problem, or if I decide that a particular problem is not very good, or if more problems of a particular kind are needed. I changed the "Homolytic Bond Dissociation Energies" problems today. There was a problem with problem #2, now fixed, and I added new problem numbers 3 and 8. Please remember to hit the "refresh" button on your browser on the appropriate pages to make sure that you see the latest versions of these problems. More... |

Sept. 7, 2011 I received an email asking about Question #10 on Quiz #3. The student submitted a picture of a model that they were trying to use to solve the problem. However, the model was not quite correct, here is my response, which should hopefully help other students in the class: I am afraid that your model is not quite correct (click HERE to see the submitted picture of the model) You need to add the "plates" that represent the atomic orbitals that are used to make the 2 pi-bonds To do this you will need to use an sp hybridized atom in the middle, the grey atom works well for this (it has more holes than you need, just use the relevant sp "holes"). Use the holes in the central atom to hold the bonds and also the atomic orbitals The inexpensive HGS kit that you have has 4 of the orbital plates, which strictly isn't enough, since each pi-bond really needs all 4 (1 on each atom in the double bond "above" and 1 on each atom "below"), but you don't have to put the orbitals both above and below the atoms for each pi-bond, just use one pair to represent one of the pi-bonds "above" the atoms, and another pair to represent the other bond "above" the atoms. You can ignore the colors of the plates, you are just trying to get the geometry correct here, don't worry about the phasing or anything like that. For each pi-bond you will build just the top "half" of the pi-bond shown in the model on page 10 of the bonding II notes OR, you can get together with someone else in the class and build two complete pi-bonds! Getting the orientation of the p atomic orbitals correct is the key to answering this question, good luck! |

Most of the office hours will consist of a problem-solving review session where we will do more practice working with stereo and structural isomers and related problems, probably including a little VSEPR and hybridization. We will not review Molecular Orbitals yet, because we still haven't finished talking about them in class, we will do M.O.s next week. I will be available after the problem session for 1-on-1 questions in PS H-150. The review session will be recorded and posted online just like the lectures. |

Sept. 2, 2011 Today's lecture has been posted. A lot of what was discussed today and in the last lecture is difficult to understand for structures that are drawn 2D on paper, the molecular shapes and the 3D locations of the electrons in space are important to understand. So, it may be useful for you to take a look at the following mini-movies that illustrate the tetrahedral geometry, click HERE, the trigonal planar geometry, click HERE, and the linear geometry, click HERE.

Aug 31, 2011 Well, I there seems to be all sorts of problems at the start of this semester. First we were locked out of the classroom on Monday, and then this morning my Table PC completely died! I had to give lecture today on the board (back to the stone age!) and I have yet to secure a replacement Tablet PC so that I can record todays lecture. I will borrow a Tablet before the end of the day, but there will be a delay in posting today's lecture, apologies! UPDATE at 6PM. I have now posted todays recorded lecture, it is a repeat of what was covered in class on the board today. The recorded lecture is significantly shorter than 50 minutes, which illustrates how much writing on the board slows me down! I have also noticed that when I record lectures in my office I tend to go a little faster, which is why I like to record the lectures for the online class in front of a class, not in my office, so that I don't go too fast. So, if I went a little fast on this recorded lecture, well that is what the pause and rewind buttons are for! Thanks for your understanding, and I hope that we have now had our share of technical difficulties for the semester. More... |

Aug 29, 2011 Those of you who attended class today will know that the classroom was locked at 7:30AM this morning, and that we missed almost the first 20 minutes of class. Therefore, I decided to skip the functional group part at the end of Section A of the notes and started Section B, Bonding II. Therefore, lecture #5 starts at the start of Section B. Later today I will post a short lecture on functional groups online that everybody can watch. The functional group part of the lecture has very little intellectual content, it is mainly naming, and so you will not lose very much by watching this part online instead of in class. More... |

Aug 24, 2011 There is a typo in question #13 of the stereoisomers problems on page 12 in the Bonding I notes. The molecular formula should be C4H8O, not C4H9O. This has been corrected on the website, but is an error in your printed gapped notes. More... |

Aug 24, 2011 For some more detailed looks at the concepts discussed today in class with respect to isomerism and bond rotation (or lack of!), you can take a look at the three short videos, HERE, HERE, and HERE. And, for one of the problems that was discussed in class, another view is given HERE. |

Aug 19, 2011 So, somehow, instead of "gapped notes", I managed to distributed COMPLETED notes in class today! Apologies. Anyway, the gapped notes are on the website and the complete set of gapped notes for the course will be available for purchase at the Alternative Copy Shop on Monday August 22nd. To get what I intended to distribute in class today, click HERE More... |

Aug 15, 2011 This class uses "gapped" lecture notes that you complete in class. They are available as pdf files under the Lecture Material tab. You can print these and bring them to lecture, or you can save money by purchasing the entire notes set from The Alternative Copy Shop, at the southwest corner of Mill Ave. and 10th street. The cost should be ca. $16 or so, give them a call before you go to make sure that they have some copies in stock (480) 829-7992. They should will be available for pickup on Monday August 22nd. I will distribute gapped notes in the first class that will last the first 2 or 3 lectures. You can also get the notes for these first lectures by printing the first 8 pages of the "Bonding and Structure I notes", click HERE. More... |

Aug 8, 2011 The recommended textbook for this class is Organic Chemistry, 3rd Edition, by J.G. Smith. If you use the textbook it is critical that you also get the accompanying Solutions Manual, since the problems are the MOST IMPORTANT part of the textbook. To keep costs down for students, we have negotiated two special paperback Textbook/Solutions Manual packages, one for CHM 233 and one for CHM 234, that are available at the ASU bookstore. The cost of the ASU special packages is probably lower than you will be able to find elsewhere for a Textbook/Solution Manual combo. If you get a 3rd Edition textbook somewhere else, please make sure that you also get the Solutions Manual. The ASU special editions do not include chapters on topics such as proteins, nucleic acids, carbohydrates etc., since these topics are not covered at ASU. We aim to teach the best organic chemistry course possible, and this will not include a superficial overview of biochemical molecules. To understand biochemical molecules properly you will need to take a biochemistry course. I will provide suggested reading and problems from the 3rd Edition of Smith ONLY. I will not be able to suggest reading or problems from any earlier edition of Smith, or from any other textbook. If you have any other textbook, it should be fairly easy for you to find the appropriate reading and problems yourself. The Textbook is recommended, not required. Many students will ask me if they should buy the textbook. Unfortunately I am not able to give a satisfactory answer, since different students have very different needs. Some students really need to study from a textbook and appreciate the chance to read about a topic from a perspective that is different from that of the instructor. Also, some students want a permanent textbook to study for the MCAT, for example. Some students will not need a textbook at all, since there is a lot of learning material on the class website. It is also true that you can learn most of what you need to know from just about any organic textbook. You have to make your own decision on this I am afraid! Note that the lab is a separate course, the textbook for the lab course is REQUIRED! A Molecular Model Kit, IS REQUIRED for CHM 233. The best kit for use in this class is the HGS 1013/1013A Organic Chemistry Set for Students (click here). The bookstore sells a more sophisticated (and expensive) version of the HGS kit, 1003 Organic Chemistry set C, that is obviously very good, however, the less expensive 1013 version works well enough for CHM 233. The 1013/1013A kit is available from Amazon, for ca. $20. Also acceptable (but not quite as good) is the Molecular Visions Darling Molecular Model Kit that may available in the bookstore. The bookstore may also have some of the Prentice Hall Molecular Model Set For Organic Chemistry (click here), but if they do, DO NOT BUY IT. It makes pretty models but is terrible for CHM 233. . |

Aug 8, 2011 It is not possible for me to give an override into this class since I am not allowed to override the reserved seat assignments or the room capacity. If you really want to get into this class, come during the first week and be persistent in trying to register online. There will be a lot of drop/add activity during the first week, persistence usually pays off. Remember that the class is offered both in the regular onground lecture format (SLN 71188) and also as an online/hybrid version (SLN 86124). Both classes are basically identical. If you are registered for the online/hybrid class you are welcome to attend lecture with the regular class. |
