Carboxylic acids do not give reactions of aldehydes and ketones why ?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Structure of Carboxylic Acids**:
Carboxylic acids have the general formula RCOOH, where R is an alkyl or aryl group. The functional group consists of a carbonyl (C=O) and a hydroxyl group (–OH).

2. **Resonance in Carboxylic Acids**:
Carboxylic acids exhibit resonance due to the presence of the carbonyl and hydroxyl groups. The lone pair of electrons on the oxygen atom of the hydroxyl group can delocalize, creating multiple resonance structures. This resonance stabilizes the carboxylic acid and affects its reactivity.
