concerted mechanisms in that formation of the new bonds occurs almost simul-
taneously. Arrow pushing is illustrated below:
2. Place the partial charges on the following molecules.
Carbonyls are polarized such that a partial negative charge resides on the oxygen
and a partial positive charge resides on the carbon.
Because of the polarity of the carbonyl, adjacent groups are also polarized. In
general, where a partial positive charge rests, an adjacent atom will bear a
partial negative charge.
