Vedclass · Answer

(D) Nuclear iodination of aromatic compounds is a reversible electrophilic substitution reaction.$I_{2}$ is a weak electrophile and the reaction produces $HI$ as a byproduct, which is a strong reducing agent and can reduce the iodinated product back to the starting material.To drive the reaction forward, an oxidizing agent like $HNO_{3}$ is used to oxidize $HI$ to $I_{2}$, thereby preventing the reverse reaction.$2HI + 2HNO_{3} \rightarrow I_{2} + 2NO_{2} + 2H_{2}O$.Thus, $I_{2} / HNO_{3}$ is the best reagent for this purpose.
