(ii) Why is the boiling point of acid anhydride higher than the acid from which it is obtained ?

Explanation

To understand why the boiling point of acid anhydrides is higher than that of the corresponding acids from which they are derived, we can break down the explanation into several key points:

### Step-by-Step Solution:

1. **Definition of Acid Anhydrides**:
- Acid anhydrides are derived from acids by the removal of water. For example, acetic acid (CH3COOH) can be converted into acetic anhydride ((CH3CO)2O) by the removal of water.

2. **Molecular Structure**:
