Question

How to convert: (1) benzene to nitro benzene. (2) benzene to methyl benzene. (3) benzene to cyclo hexane. (4) ethyne to benzene

Answer 1

1. Benzene is heated with nitrating mixture to form nitrobenzene.The reaction is known as .It is aromatic electrophilic substitution reaction.



Mechanism:—

Mechanism of nitration of benzene is simple and two stepped. First step consists of attack of nitronium ions on the benzene ring to form aerenium ion.

In second step aerenium ion loses proton to form niteobenzene.

2.
Convert Benzene to Benzoic acid via Friedel Craft's alkylation followed by oxidation with Potassium Permanganate.
