Conversion of Aniline to bromobenzene

Explanation

To convert aniline to bromobenzene, we will follow these steps:

### Step 1: Diazotization of Aniline
- **Reaction**: Treat aniline (C6H5NH2) with sodium nitrite (NaNO2) and hydrochloric acid (HCl) at a temperature of 0 to 5 degrees Celsius.
- **Products**: This reaction will produce benzenediazonium chloride (C6H5N2Cl). The reaction can be represented as:

\[
C6H5NH2 + NaNO2 + HCl \rightarrow C6H5N2Cl + NaCl + 2H2O
