Vedclass · Answer

(D) Chlorofluorocarbons (CFCs) such as $CF_2Cl_2$ (Freon-$12$),$CFCl_3$,and other halogenated compounds are responsible for ozone layer depletion.These compounds release chlorine radicals in the stratosphere upon exposure to ultraviolet radiation:$CF_2Cl_2 \xrightarrow{h
u} \dot{Cl} + \dot{CF}_2Cl$These chlorine radicals then react with ozone $(O_3)$:$\dot{Cl} + O_3 \longrightarrow \dot{ClO} + O_2$$\dot{ClO} + O \longrightarrow \dot{Cl} + O_2$Thus,$CF_2Cl_2$ is the correct answer.
