Vedclass · Answer

(B) Iodination of alkanes is a reversible reaction because the $HI$ formed acts as a strong reducing agent and reduces the alkyl iodide back to the alkane.To make the reaction proceed in the forward direction,the $HI$ must be removed.This is achieved by adding an oxidizing agent like $HIO_3$ or $HNO_3$,which oxidizes $HI$ to $I_2$.The reaction is as follows:$5HI + HIO_3 \rightarrow 3I_2 + 3H_2O$$CH_4 + I_2 \rightleftharpoons CH_3I + HI$
