Bromobenzene to styrene (in 4 Steps)

Explanation

To convert bromobenzene to styrene in four steps, we can follow these steps:

### Step 1: Friedel-Crafts Alkylation
- **Reaction**: Bromobenzene (C6H5Br) is treated with ethyl chloride (C2H5Cl) in the presence of aluminum chloride (AlCl3).
- **Mechanism**: AlCl3 acts as a Lewis acid and generates an ethyl cation (C2H5+). The benzene ring acts as a nucleophile and attacks the ethyl cation, leading to the formation of ethylbenzene (C6H5C2H5).

**Equation**:
