In stratosphere the following reactions takes place which are responsible for depletion of ozone layer. $\begin{aligned} & \mathrm{NO}+\mathrm{O}_3 \longrightarrow \mathrm{NO}_2+\mathrm{O}_2 \ & \mathrm{CF}_2 \mathrm{Cl}_2 \stackrel{h v}{\longrightarrow} \dot{\mathrm{C}} \mathrm{F}_2 \mathrm{Cl}+\dot{\mathrm{Cl}} \ & \mathrm{CFCl}_3 \stackrel{h v}{\longrightarrow} \dot{\mathrm{C}} \mathrm{FCl}_2+\dot{\mathrm{C}} \mathrm{l} \ & \dot{\mathrm{C}} 1+\mathrm{O}_3 \longrightarrow \mathrm{Cl} \dot{\mathrm{O}}+\mathrm{O}_2 \ & \mathrm{Cl} \dot{\mathrm{O}}+\mathrm{O} \longrightarrow \dot{\mathrm{C}}+\mathrm{O}_2 \ & \end{aligned}$ Hence, methane $\left(\mathrm{CH}_4ight)$ is not responsible for ozone layer depletion.
