CH3I cannot be prepared by direct iodination of methane as the reaction is slow and reversible. However, it can be prepared by carrying out the reaction in the presence of
Show Hint
Remember: Iodination requires an oxidizing agent (\(HIO_3\)/\(HNO_3\)), while bromination and chlorination do not, as \(HBr\) and \(HCl\) are not strong enough reducing agents to reverse the reaction easily.
