Chlorination of benzene in presence of light

WebApr 7, 2024 · When chlorination of ethylbenzene is carried out in presence of heat or light, 1-chloro-1-phenylethane is obtained as the major product. In this reaction, chlorine enters the alkyl side chain and aromatic benzene ring is not affected. Web15) Undesired polysubstitution of an aromatic nucleus is most likely to be encountered in the case of: a) Friedel-Crafts alkylation. 16) This substituent deactivates the benzene ring towards electrophilic substitution but directs the incoming group chiefly to the ortho and para positions. c) -F.

Webanalogous chlorination reaction using Cl 2 and FeCl 3 gives chlorobenzene. This reaction of benzene with halogens differs from the reaction of alkenes with halogens in two important ways. First is the type of product obtained. Alkenes react spontaneously with bromine and chlorine, even in dilute solution, to give addition products. First step: Chloronium ion formation, chlorine react with the Lewis acid to form a complex which makes the chlorine more electrophile. Second step: Chloronium ion attack on the ring.
