$p$-Nitroethylbenzene

Vedclass · Answer

(B) Ethylbenzene reacts with dilute nitric acid under specific conditions,but typically,dilute nitric acid is not a strong enough nitrating agent to perform electrophilic aromatic substitution on the benzene ring of ethylbenzene effectively. However,if the reaction is considered in the context of standard organic chemistry problems,the alkyl group $(-CH_2CH_3)$ is an ortho/para directing group. Therefore,the expected products of nitration would be a mixture of $o$-nitroethylbenzene and $p$-nitroethylbenzene. Given the options,both $A$ and $B$ are valid isomers,but usually,$p$-nitroethylbenzene is the major product due to steric hindrance at the ortho position. If the question implies a specific reaction condition leading to a single major product,$p$-nitroethylbenzene is the standard answer.
