Convert `C_(6)H_(6) ` to `C_(6)H_(5)D`

Explanation

To convert benzene (C₆H₆) to deuterated benzene (C₆H₅D), we can follow these steps:

### Step 1: Bromination of Benzene
- **Reaction**: Benzene (C₆H₆) is treated with bromine (Br₂) in the presence of anhydrous aluminum bromide (AlBr₃) as a catalyst.
- **Product**: This reaction leads to the formation of bromobenzene (C₆H₅Br).

### Step 2: Formation of Grignard Reagent
- **Reaction**: Bromobenzene (C₆H₅Br) is then reacted with magnesium (Mg) in an ether solvent.
