Which chemical are responsible for the …

The chemicals responsible for ozone layer destruction are: Chlorofluorocarbons: Chlorofluorocarbons (CFCs) are non-toxic, non-flammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. Halogens: Ozone is destroyed by reactions with chlorine, bromine, nitrogen, hydrogen, and oxygen gases. Reactions with these gases typically occur through catalytic processes. Because of catalytic reactions, an individual chlorine atom, on an average, can destroy nearly a thousand ozone molecules, before it is converted into a form harmless to ozone. Hydrofluorocarbons: The HFCs are a class of replacements for CFCs and affect the ozone layer.
