Explanation:
Detailed explanation-1: -CFCs and HCFCs are usually produced by halogen exchange starting from chlorinated methanes and ethanes. The brominated derivatives are generated by free-radical reactions of the chlorofluorocarbons, replacing C-H bonds with C-Br bonds. The most common CFCs are small molecules containing only one or two carbon atoms.
Detailed explanation-2: -Refrigerators, air conditioners, different types of sprays, fire extinguishers, and paints released chlorofluorocarbons in the air. And this emission contributed to the depletion of the Ozone layer.
