Q  how will you convert benzene into

1. P-nitrochlorobenzene          2. M-nitrochlorobenzene  

3. acetophenone                        4. P-nitrotoluene

2.  by nitration using H₂SO₄ (CONC.) and HNO₃  and then chlorination.

3. by freidal crafts acylation.

 1.  The Bromination of benzene in presence of Ferric chloride produces Bromobenzene the nitration of bromobenzene with dilute nitric acid gives ortho and para products which may be separated by physical means.

4. By Friedel crafts acylation, ie treating benzene with any CH₃COX, where X is a halide.
