Ethylbenzene is generally prepared by acetylation of benzene followed by reduction and not by direct alkylation.Why?

Options

1. ADirect alkylation of benzene with ethyl groups is a highly exothermic reaction.
2. BAcetylation followed by reduction provides a better yield of ethylbenzene.
3. CThe direct alkylation cannot be performed because a poly-substituted product is also formed. After the monoalk
4. DAcetylation of benzene is a more cost-effective and readily available process.
