Q.
Arrange the correct sequence for mechanism of chlorination of methane
I. $CH _{4}+ Cl ^{\bullet} \xrightarrow{h v} \overset{\bullet}{ C}H _{3}+ H - Cl$
II. $Cl - Cl \xrightarrow{h v } 2 \overset{\bullet}{ C}l $
III. $\overset{\bullet}{C}H _{3}+ Cl _{2} \longrightarrow CH _{3}- Cl + Cl ^{\bullet}$
IV. $\overset{\bullet}{ C}l +\overset{\bullet}{ C}l \longrightarrow Cl - Cl$
$\overset{\bullet}{C}H _{3}+ \overset{\bullet}{C}H _{3} \longrightarrow CH _{3}- CH _{3}$
Choose the correct option.
