Vedclass · Answer

(D) The electrophilic substitution reaction of benzene with iodine $(I_2)$ is a reversible process. The reaction is as follows: $C_6H_6 + I_2 \rightleftharpoons C_6H_5I + HI$. Because the byproduct $HI$ is a strong reducing agent,it reduces the iodobenzene back to benzene,making the forward reaction unfavorable. Therefore,direct iodination of benzene is not possible without the presence of an oxidizing agent (like $HNO_3$ or $HIO_3$) to consume the $HI$ produced.

Which of the following reactions is not possible for benzene due to its reversible nature?
