Question

Which of the following substitution reaction with methane requires HIO\(_3\) as an oxidising agent?

• A. Chlorination
• B. Bromination
• C. Iodination
• D. Fluorination
• E. Friel-Crafts acylation

Hint:

Iodination of methane typically requires an oxidizing agent like HIO\(_3\) to enhance the reactivity of iodine.

Answer 1

The Correct Option is C

In the iodination of methane, the presence of an oxidizing agent like HIO\(_3\) is required because iodine has a relatively low reactivity. HIO\(_3\) helps facilitate the substitution reaction by oxidizing iodine. 
Thus, the correct answer is (C).
