Question
Alkane can be iodinated in the presence of:
✓

Answer

Iodination of an alkane is carried out in the presence of oxidizing agent because one of the products of this reaction is hydrogen iodide and this is a strong reducing agent and converts alkyl iodide back to an alkane.
Therefore to counter this difficulty, the iodination of alkanes are carried out in the presence of a strong oxidizing agent like iodic acid $\ce{(HIO_3​)}$ which oxidizes the hydrogen iodide formed.
