Vedclass · Answer

(C) Chlorofluorocarbons $(CFCs)$ are the main cause of ozone depletion.In the presence of $UV$ radiation,$CFCs$ release chlorine radicals $(Cl^{\bullet})$.$CF_2Cl_{2(g)} \stackrel{UV}{\longrightarrow} \dot{Cl}_{(g)} + \dot{C}F_2Cl_{(g)}$These chlorine radicals react with ozone $(O_3)$ to form chlorine monoxide $(ClO)$ and oxygen $(O_2)$:$\dot{Cl}_{(g)} + O_{3(g)} \longrightarrow ClO_{(g)} + O_{2(g)}$Then,$ClO$ reacts with atomic oxygen to regenerate the chlorine radical:$Cl\dot{O}_{(g)} + O_{(g)} \longrightarrow \dot{Cl}_{(g)} + O_{2(g)}$Thus,$Cl^{\bullet}$ is the radical that mainly causes ozone depletion.

The radical which mainly causes ozone depletion in the presence of $UV$ radiations is:
