The Concept of Resonance,act at all with many of the reagents (weak nucleophiles) which attack the carbonyl group in aldehydes and ketones. It would appear that when these two functional groups are adjacent to one another, they are each able to modify the properties of the other in a way which would not be predicted from the Lewis formula*.

Nucleophilic Reactions of Carboxylic Acids and their Derivatives,of chemical reactivity. In fact, although they are often attacked by the same nucleophiles which react with aldehydes and ketones, the presence of another reactive group such as chloro (acid chlorides) or amino (acid amides) considerably modifies the behaviour of these compounds.
