Question

The reaction that is not involved in the ozone layer depletion mechanism in the stratosphere is, $ \mathrm{CH}_{4}+2 \mathrm{O}_{2} \rightarrow \mathrm{CO}_{2}+2 \mathrm{H}_{2} \mathrm{O} $, $ \mathrm{Cl} \stackrel{\circ}{\mathrm{O}}(\mathrm{g})+\mathrm{O}(\mathrm{g}) \rightarrow \dot{\mathrm{Cl}}(\mathrm{g})+\mathrm{O}_{2}(\mathrm{~g}) $, $ \mathrm{CF}_{2} \mathrm{Cl}_{2}(\mathrm{~g}) \stackrel{\mathrm{uv}}{\longrightarrow} \dot{\mathrm{Cl}}(\mathrm{g})+\dot{\mathrm{CF}}_{2} \mathrm{Cl}(\mathrm{g}) $, $ \mathrm{HOCl}(\mathrm{g}) \stackrel{\mathrm{h}(\mathrm{nu})}{\longrightarrow} \dot{\mathrm{O} \mathrm{H}}(\mathrm{g})+\dot{\mathrm{Cl}}(\mathrm{g}) $

Methane oxidation is responsible for the majority of ozone formation in troposphere. Hence, the process is not involved in the ozone layer depletion mechanism in the stratosphere.
