Vedclass · Answer

(C) The compounds $CF_xCly$ where $x + y = 4$ are known as chlorofluorocarbons (CFCs),commonly referred to as Freons.These compounds are widely used as refrigerants and in aerosol propellants.However,they are considered environmentally harmful because they are chemically inert and stable in the lower atmosphere.When they reach the stratosphere,they are broken down by ultraviolet radiation to release chlorine free radicals $(Cl^\bullet)$.These chlorine radicals catalyze the breakdown of ozone $(O_3)$ into oxygen $(O_2)$,leading to the depletion of the ozone layer.
