Chlorofluoro carbons (CFCs) such as $\mathrm{CF}_2 \mathrm{Cl}_2$, $\mathrm{CFCl}_3$, hydrofluoro carbons (HFCs) are responsible for ozone layer depletion or ozone holes. $\begin{aligned} & \mathrm{CF}_2 \mathrm{Cl}_2 \stackrel{h v}{\longrightarrow} \dot{\mathrm{Cl}}+\dot{\mathrm{CF}}_2 \mathrm{Cl} \ & \dot{\mathrm{Cl}}+\mathrm{O} \longrightarrow \overrightarrow{\mathrm{ClO}}+\mathrm{O}_2 \ & \dot{\mathrm{ClO}}+\mathrm{O} \longrightarrow \dot{\mathrm{Cl}}+\mathrm{O}_2\end{aligned}$
