Explanation:
Detailed explanation-1: -This reaction is an example of substitution reaction.
Detailed explanation-2: -The initiation step involves the formation of a methyl free radical. One of the propagation steps is represented by the equation: CH4 + Cl 4 HCI + CHze One of the termination steps is represented by equation: CH; o CH3’ CzH6 The reaction can take place in the dark if methyl free radicals are added.
