Give reasons for the following : (iii) `R-COOH` do not give characteristic reaction with `gt C=O`.

Explanation

To understand why carboxylic acids (R-COOH) do not give characteristic reactions with carbonyl compounds (like aldehydes and ketones), we need to analyze the structure and reactivity of these compounds.

### Step-by-Step Solution:

1. **Identify the Functional Groups**:
- Carboxylic acid (R-COOH) contains a carboxyl group (-COOH).
- Aldehydes (R-CHO) and ketones (R-CO-R') contain a carbonyl group (C=O).
