Vedclass · Answer

(B) The synthesis of $1$-butyl-$4$-nitrobenzene involves the following steps:$1$. Friedel-Crafts acylation of benzene with butanoyl chloride $(CH_3CH_2CH_2COCl)$ in the presence of $AlCl_3$ gives $1$-phenylbutan-$1$-one.$2$. Clemmensen reduction of the ketone using $Zn/Hg$ and $HCl$ with heat reduces the carbonyl group to a methylene group,yielding butylbenzene.$3$. Nitration of butylbenzene using a mixture of concentrated $HNO_3$ and $H_2SO_4$ introduces the nitro group at the para position because the alkyl group is an ortho/para-directing group.

Identify the correct method for the synthesis of the compound shown below from the following alternatives.
