How will you obtain monobromobenzene from aniline ?

Explanation

To obtain monobromobenzene from aniline, we can follow these steps:

### Step 1: Formation of Benzene Diazonium Chloride
1. **Start with Aniline**: Aniline (C6H5NH2) is our starting compound.
2. **Dissolve in Cold Aqueous Mineral Acid**: Dissolve aniline in cold aqueous mineral acid, which is typically sodium nitrite (NaNO2) in the presence of hydrochloric acid (HCl).
3. **Maintain Temperature**: Keep the temperature between 273 K to 373 K (0 °C to 100 °C).
4. **Formation of Benzene Diazonium Chloride**: This reaction will lead to the formation of benzene diazonium chloride (C6H5N2Cl).
