State the equation for the preparation of following compound.
Chlorobenzene from aniline (in 2 steps).

Explanation

To prepare chlorobenzene from aniline in two steps, we can follow these reactions:

### Step 1: Conversion of Aniline to Benzonitrile
1. **React Aniline with Alcoholic Potassium Cyanide (KCN)**:
\[ \text{C}_6\text{H}_5\text{NH}_2 + \text{KCN} \xrightarrow{\text{Alcoholic}} \text{C}_6\text{H}_5\text{CN} + \text{KOH} \]
In this step, aniline (C₆H₅NH₂) reacts with alcoholic KCN to form benzonitrile (C₆H₅CN) and potassium hydroxide (KOH).
