Question

Benzene cannot be iodinated with I 2 directly. However, in presence of oxidants such as H N O 3 , iodination is possible. The electrophiles formed in the case is, I +, I -, I +δ ...... O +δ H 2 +, I − δ ...... O − δ H 2 +

MARKS App · Accepted Answer

In the presence of oxidising agents such as H N O 3 direct, iodination of benzene is possible. The electrophiles formed in this case is I + . H + + HNO 3 + 1 2 I 2 → I + Iodine cation + NO 2 + H 2 O
