Question

Write the reactions of anisole with
( i) Br2 in ethanoic acid
(ii)CH3Cl in presence of Anhydrous AlCl3
(iii) CH3COCl in presence of Anhydrous AlCl3
(iv) HNO3 in presence of H2SO4​

Answer 1

Explanation:

When anisole is treated with CH

3

Cl in presence of anhydrous AlCl

3

, a mixture of ortho and para methyl anisole is produced.

Anisole undergoes Friedel-Crafts alkylation reaction with an alkyl halide in presence of Lewis acid AlCl

3 as a catalyst.

solution

or

when benzene is treated with an alkyl halide in the presence of anhydrous aluminium chloride it gives alkylbenzene. In this reaction hydrogen atom of benzene is replaced by an alkyl group. The reaction is called as Friedel-Craft's alkylation reaction. In this reaction alkyl groups are electrophiles and role of aluminium chloride is to generate these electrophiles. In the given reaction Benzene reacts with methyl chloride to give methylbenzene or toluene.
