Vedclass · Answer

(C) In the Friedel-Crafts alkylation of benzene,the alkyl group introduced is electron-donating,which activates the benzene ring towards further electrophilic substitution. This leads to the formation of polyalkylated products. In contrast,the acyl group introduced in acylation is electron-withdrawing,which deactivates the ring and prevents further substitution,ensuring the formation of a mono-acylated product. Therefore,acylation is preferred,followed by the reduction of the carbonyl group to a methylene group to obtain the desired alkyl benzene.

Acylation process is preferred over direct alkylation in the Friedel-Crafts reaction because:
