Question

starting from benzene prepare m- nitrotoluene

Answer 1

I have suggested the preparation of meta nitro toluene from Benzene in the attachment

I have also suggested an alternative method.

hope it helps!

Answer 2

Answer:

The mixture of p-nitrotoluene and the o-nitrotoluene can be separated by the fractional distillation. Thus, benzene is converted into p-nitrotoluene by converting benzene to toluene then the toluene to a mixture of o-nitrotoluene and p-nitrotoluene and then separating the mixture by fractional distillation to get p-nitrotoluene

Explanation:

Friedel crafts of  alkylation of benzene with the methyl chloride in the  presence of anhydrous aluminium chloride gives toluene.

nitration of toluene with the  mixture of dil-nitric acid and dil-sulphuric acid gives a mixture of ortho and para nitro toluene which are separated by the fractional distillation.

benzene + HNO3 + H2SO4 → nitrobenzene
