Aryl chlorides and bromides can be easily prepared by electrophilic substitution of arenes with chlorine and bromine respectively in the presence of Lewis acid catalysts. But why does preparation of aryl iodides requires presence of an oxidizing agent?

Options

1. AAryl iodides are more stable than aryl chlorides and bromides, so an oxidizing agent is needed to increase the
2. BBecause Iodination reactions are reversible in nature. To carry out the reaction in the forward direction, HI
3. CAryl iodides are less reactive than aryl chlorides and bromides, so an oxidizing agent is used to activate iod
4. DAryl iodides have a higher boiling point than aryl chlorides and bromides, so an oxidizing agent is used to re
