1.	Suggest theroute for the preparation of the followingfrom benzene 1 3-chloro nitrobenzene 2 4-chlorotoluene 3 Bromobenzene 4 m-dinitrobenzene
Answer» Solution :Preparation of 3-chloronitro - BENZENE from benzene : Benzene undergoes nitration and followed by chlorination and it LEADS to the formation of 3-chloronitrobenzene . 2. Preparation 4-chlorotoluence from benzene : Benzene undergoes FRIEDEL cradf.s alkylation followed by chlorination and it leads to formation of 4-chlorotoluene. 3. Preparation of Bromobenzene from benzene : Benzene undergo bromination to give bromobenzene . 4. preparation of m-dintrobenzene from benzene : Benzene undergo twice the TIME nitration to give m-dinitrobenzene.
