How will you convert benzene into (a) p-nitrobromobenzene (b) m-nitrobromobenzene

Explanation

To convert benzene into p-nitrobromobenzene and m-nitrobromobenzene, we can follow these steps:

### (a) Conversion of Benzene to p-Nitrobromobenzene

1. **Bromination of Benzene**:
- Start with benzene (C6H6).
- Perform bromination using bromine (Br2) in the presence of a Lewis acid catalyst like FeBr3.
- This will lead to the formation of bromobenzene (C6H5Br) through an electrophilic aromatic substitution reaction, where one hydrogen atom of benzene is replaced by a bromine atom.
