MCQ
Alkane can be iodinated in the presence of:
- A$HI$
- B$I_2$ and $P$
- ✓$\ce{HIO_3}$
- D$PI_3$
✓
Answer
Correct option: C.
$\ce{HIO_3}$
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.
