Chlorination of methane is a free radical reaction which occurs by the following mechanism involving initiation, propagation and termination steps:
From the above mechanism, it is evident that during the propagation step, CH3 free radicals are produced, which may undergo three reactions, i.e., (i), (ii) and (iii). In the chain termination step, the two CH3 free radicals combine to form ethane (CH3—CH3) molecule.
