Vedclass · Answer

(C) The given reaction is a free radical halogenation of alkanes.$1$. The reactivity order of halogens is $F_2 > Cl_2 > Br_2 > I_2$. Thus,option $A$ is incorrect.$2$. The reaction proceeds via a free radical substitution mechanism,not electrophilic substitution. Thus,option $B$ is incorrect.$3$. Iodination is a reversible reaction. To drive the reaction forward and increase the yield of alkyl iodide,an oxidizing agent like $HIO_3$ or $HNO_3$ is used to consume the $HI$ produced. Thus,option $C$ is correct.
