Question

conversion of benzene to isobutyl benzene​

Answer 1

Explanation:

Synthesis of isobutylbenzene from benzene

First, a Friedel-Crafts acylation functionalizes benzene with an isobutyryl moiety (1). This substituent is reduced to an isobutyl group through a Clemmensen reduction, yielding isobutylbenzene (2).
