Answer:

Chlorofluorocarbon ( CFC )

Explanation:

Chlorofluorocarbon ( CFC ) is halogenated paraffin hydrocarbon that consists of carbon, hydrogen, fluorine and chlorine. It is derivative of methane, ethane and propane. It was used as refrigerant and propellant in aerosol cans. It triggers ozone depletion hence its manufacture has been stopped under Montreal Protocol and it has been replaced with other hydro fluorocarbons.

UV light on striking a CFC molecule in upper atmosphere, breaks the carbon chlorine bond which produces a chlorine atom. This chlorine atom reacts with an ozone molecule and destroys it. Hence, CFC damage the ozone layer of the Earth.
