Carboxylic acids contain carbonyl group but do not show the nucleophilic addition reactions like aldehydes or ketones. Why?

Explanation

To understand why carboxylic acids do not undergo nucleophilic addition reactions like aldehydes and ketones, we can break down the explanation into several key points:

### Step-by-Step Solution:

1. **Understanding Nucleophilic Addition Reactions**:
- Nucleophilic addition reactions involve the attack of a nucleophile (an electron-rich species) on an electrophile (an electron-deficient species). In the case of carbonyl compounds, the carbonyl carbon acts as the electrophile.

2. **Structure of Carboxylic Acids**:
