Definition of Chlorofluorocarbons
Chlorofluorocarbons are chemical compounds consisting of atoms of carbon, chlorine, and fluorine. These chemicals are non-toxic and inflammable. They belong to the class of compounds that have atoms of halogens and carbon in them i.e. halocarbons. They are used as refrigerants in the fridge and air conditioners, as solvents, in packing materials as blowing agents and in the manufacturing of aerosols, etc.
These CFCs are completely safe and inert but they are the source of depleting the ozone layer. One chlorine atom is enough to destroy 100,000 atoms of ozone. The ozone depletion leads to the phenomenon of global warming.
