Question

Which of the following species is not formed through a termination reaction in the chlorination of methane? Which of the following species is not formed through a termination reaction in the chlorination of methane? Cl2 CH3CH3 H2 CH3Cl

Answer 1

Explanation:

When we add chlorine to a substance or compound then this process is known as chlorination.

For example, a process of chlorination is as follows.

Initiation : $Cl_{2} \overset{light}{\rightarrow} 2Cl*$          

where, Cl* is a free radical.

Propagation:

    $Cl* + CH_{4} \rightarrow HCl + *CH_{3}$

    $CH_{3} + Cl_{2} \rightarrow CH_{3}Cl + Cl*$

Termination:

    $2Cl* \rightarrow Cl_{2}$

    $Cl* + *CH_{3} \rightarrow CH_{3}Cl$

    $2*CH_{3} \rightarrow CH_{3}-CH_{3}$

Thus, we can conclude that out of the given options $H_{2}$ is not formed through a termination reaction in the chlorination of methane.
