Assertion (A): Carboxylic acids do not give the characteristic nucleophilic addition reactions of aldehydes and ketones. Reason (R): The carbonyl carbon of carboxylic acids is more electrophilic than that of aldehydes and ketones due to the strong electron-withdrawing inductive effect of the - OH group.

Step-by-step solution

Carboxylic acids do not undergo characteristic nucleophilic addition reactions like aldehydes and ketones because the lone pair of electrons on the oxygen atom of the - OH group is involved in resonance with the carbonyl group. This resonance delocalizes the electron density, making the carbonyl carbon less electrophilic (less electron-deficient) compared to the carbonyl carbon in aldehydes and ketones. Therefore, Assertion (A) is true, but Reason (R) is false because the carbonyl carbon of carboxylic acids is less
