Conversion of Aniline to 1, 3, 5-Tribromobenzene

Explanation

To convert aniline to 1,3,5-tribromobenzene, we can follow these steps:

### Step 1: Conversion of Aniline to Diazonium Salt
- **Reaction**: Aniline (C6H5NH2) is treated with sodium nitrite (NaNO2) and hydrochloric acid (HCl) at a temperature of 0 to 5 degrees Celsius.
- **Equation**:
\[ C6H5NH2 + NaNO2 + HCl \rightarrow C6H5N2Cl + NaCl + 2H2O \]
