Carboxylic acids do not give the characteristic reactions of carbonyl group. Explain.

Text Solution

Verified by Experts


Due to structures (II) of carboxylic acids, carboxylic acid is less electrophilic. Due to structure (IV) carbonyl carbon in aldehyde and ketones in electrophilic. As a result nucleophilic addition reaction like aldehyde and Ketones do not takes place with carboxylic acids.
