Question

what is the action of the following reagent on chlorobenzene a) sodium b) methyl chloride c) sulfuric acid ​

Answer 1

When chlorobenzence is treated with methyl chloride in the presence of anhydrous AlCl3, a mixture of 1-chloro-4-methyl benzence (major product) and 1-chloro-2-methyl benzence is formed. Since, the alkyl group is introduced in the benzene ring, the reaction is termed as Friedel Crafts alkylation.
