How can the following conversions be brought about :
Acetic acid to methylamine.

Explanation

To convert acetic acid (CH3COOH) to methylamine (CH3NH2), we can follow a series of chemical reactions. Here’s a step-by-step breakdown of the process:

### Step 1: Formation of Ammonium Acetate
- **Reaction**: Acetic acid reacts with ammonia (NH3) in the presence of concentrated sulfuric acid (H2SO4).
- **Equation**:
\[ \text{CH}_3\text{COOH} + \text{NH}_3 \xrightarrow{\text{H}_2\text{SO}_4} \text{CH}_3\text{COONH}_4 \]
