How is aniline converted to benzoic acid? Discuss the reactions

Explanation

To convert aniline (C6H5NH2) to benzoic acid (C6H5COOH), we can follow these steps:

### Step 1: Formation of Diazonium Salt
1. **React aniline with nitrous acid (HNO2)**:
- Aniline is treated with nitrous acid, which can be generated in situ by mixing sodium nitrite (NaNO2) with hydrochloric acid (HCl).
- The reaction leads to the formation of benzene diazonium chloride (C6H5N2Cl).

**Reaction:**
