#1

Ethyl benzene is generally prepared by acetylation of benzene followed by the reduction and not by
direct alkylation. Think of a possible reason.


#2

Preparation of ethyl benzene from acylation of benzene yields acetophenone which on reduction gives ethyl benzene. The complete reactions can be shown as:

The direct alkylation cannot be performed because polysubstitution product is formed. Due to disadvantage of polysubstitution, the Friedel-Crafts alkylation reaction is not used for the preparation of alkyl benzene. Instead of that, Friedel-Crafts acylation is used.
