Vedclass · Answer

(B) Chlorofluorocarbons $(CFCs)$,also known as Freons,are used in refrigerators and air conditioners. When these $CFCs$ reach the stratosphere,they absorb ultraviolet radiation and release chlorine free radicals $(Cl^{\bullet})$. These chlorine free radicals act as catalysts in the depletion of the ozone layer through the following reactions: $Cl^{\bullet} + O_3 \rightarrow ClO^{\bullet} + O_2$ $ClO^{\bullet} + O \rightarrow Cl^{\bullet} + O_2$ Thus,the correct answer is $Chlorofluorocarbons$.

Chlorine atoms act as catalysts in the depletion of the ozone layer in the Earth's atmosphere. These chlorine atoms originate from which of the following?
