Detail about MCQs

Chlorofluorocarbons (CFCs) are a group of synthetic compounds containing carbon, chlorine, and fluorine. They were commonly used in aerosol sprays, refrigerants, solvents, and foam-blowing agents. When released into the atmosphere, CFCs can reach the stratosphere, where they are broken down by ultraviolet (UV) radiation, releasing chlorine atoms. These chlorine atoms then catalytically destroy ozone molecules, leading to the depletion of the ozone layer. This process is known as ozone depletion.
