What are CFCs?

CFCs are non-toxic, non-flammable, and non-carcinogenic. They contain fluoride atoms, carbon atoms, and chlorine atoms. The five main CFCs are CFC-11 (trichlorofluoromethane - CFCl3), CFC-12 (dichloro-difluoromethane - CF2Cl2), CFC-113 (trichloro-trifluoroethane - C2F3Cl3), CFC-114 (dichloro-tetrfluoroethane - C2F4Cl2), and CFC-115 (chloropentafluoroethane - C2F5Cl).

How do CFCs hurt the Ozone Layer?

The main cause of the depletion of the Ozone is determined as excessive release of chlorine and booming from man-made compounds such as CFCs. The gases are carried to the stratosphere layer of atmosphere where ultraviolet radiations from the sun break them to release chlorine and bromine from CFCs.
