Assertion: Iodination of alkanes is carried out in the presence of oxidising agents like `HIO_(3)` or `HNO_(3)`.
Reason: Iodination of alkanes is an irreversible reaction.

Text Solution

Verified by Experts

Iodination is a slow and reversible process. Hence, the HI formed in the reaction again decomposes to produces alkaline. The oxidizing agents prevent the formation of alkane of alkane back by decomposing HI into iodine.
