Conversion of Aniline to Benzonitrile

Explanation

To convert Aniline to Benzonitrile, we will follow a two-step process involving diazotization and the St. Mary's reaction. Here’s a step-by-step breakdown of the conversion:

### Step 1: Diazotization
1. **Starting Material**: Aniline (C6H5NH2)
2. **Reagents**: Sodium nitrite (NaNO2) and Hydrochloric acid (HCl) at low temperatures (0-5°C).
3. **Reaction**:
- Mix aniline with HCl to form anilinium chloride.
- Add sodium nitrite to the solution to form the diazonium salt.
