Conversion of Aniline into nitrobenzene (without the intermediacy of benzene)

Explanation

To convert aniline into nitrobenzene without using benzene as an intermediate, we can follow these steps:

### Step 1: Formation of Diazonium Salt
1. **Starting Material**: Begin with aniline (C6H5NH2).
2. **Reagents**: Treat aniline with sodium nitrite (NaNO2) in the presence of hydrochloric acid (HCl) at a low temperature (0 to 5 °C).
3. **Reaction**: The reaction produces diazonium salt (C6H5N2Cl).
- **Equation**:
