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
  1. I +
  2. I -
  3. I ...... O H 2 +
  4. I δ ...... O δ H 2 +

Solution

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 ^
