    When methane is chlorinated, the products formed also contains traces of chloroethane. How will you account for it?

    Answer:

                    We know that the chlorination of methane proceeds by free radical mechanism in which methyl free radical \[(\overset{\centerdot }{\mathop{C}}\,{{H}_{3}})\] is formed. Two such free radicals may combine to give ethane which upon further chlorination gives chloroethane. \[\overset{\centerdot }{\mathop{C}}\,{{H}_{3}}+\overset{\centerdot }{\mathop{C}}\,{{H}_{3}}\xrightarrow{{}}\underset{\text{Ethane}}{\mathop{C{{H}_{3}}-C{{H}_{3}}}}\,\xrightarrow[(hv)]{C{{l}_{2}}}\]\[\underset{\text{Chloroethane}}{\mathop{C{{H}_{3}}-C{{H}_{2}}Cl}}\,+HCl\]
