Vedclass · Answer

(A) Chlorofluorocarbons $(CFCs)$,such as $CCl_2F_2$ (Freon-$12$),are stable compounds that reach the stratosphere. In the stratosphere,they undergo photochemical decomposition by ultraviolet radiation to release chlorine free radicals $(Cl^{\bullet})$. These chlorine radicals react with ozone $(O_3)$ to convert it into oxygen $(O_2)$,leading to the depletion of the ozone layer. Therefore,the statement that $CCl_2F_2$ causes ozone depletion is true.

The depletion of ozone in the atmosphere by chlorofluorocarbons [$CCl_2F_2$] is a ...... statement.
