Resonance Contributors |
|
|
|
In the problems below,
draw the missing resonance contributor, use curved arrow pushing to show how
the various contributors are related, indicate the major and minor
contributors, and draw "actual" structures indicting the fractional
charges on the relevant atoms. The worked examples are in the form of Flash
files, you will need to install the latest Flash Player to view them
properly.
