Vedclass · Answer

(D) Chlorofluorocarbons (CFCs),commonly known as freons,are stable compounds that reach the stratosphere. In the presence of ultraviolet radiation,they release chlorine atoms,which catalytically destroy ozone $(O_3)$ molecules,leading to the depletion of the ozone layer. Similarly,nitrogen dioxide $(NO_2)$ also contributes to the depletion of the ozone layer through complex chemical reactions in the stratosphere.

The common refrigerant chlorofluoromethane (freon) and $NO_2$ are serious pollutants because
