Freon is a registered trademark of The Chemours Company, which uses it for a number of halocarbon products. They are stable, nonflammable, moderately toxic gases or liquids which have typically been used as refrigerants and as aerosol propellants.

Hi,
Here is your answer,
The chlorofluorocarbon of methane and ethane are collectively known as freons. Some of the derivatives are:-CHF₂Cl (monochlorodifluoromethane), CF₂Cl₂ (dichlorodifluoromethane), HCF₂CHCl₂ (1,1-dichloro-2,2-difluoro ethane)etc,
They are extremely stable, unreactive, non-toxic, non-corrosive and easily liquefiable gases. The most important and useful derivative is CF₂Cl₂ which is commonly known as freon or freon-12. It is manufactured from tetrachloromethane by ''SWARTS REACTION''. It can be easily liquefied and chemically inert.
Freons are used for aerosal propellants, refrigeration and air conditioning purposes. Since freons have been found to be the factors responsible for the depletion of ozone layers, they are being replaced by other harmless compounds. In refrigerators and automotive air conditioners, Freon-12 has been replaced by Freon-22 CHC/F₂. Freons with C-H bonds (such as Freon-22), called HCFCs, are generally destroyed at lower altitudes before they reach the stratosphere. HCFC-123 (CHCl₂CF₃) is used as a substitute for Freon-11 in making plastic foams.
Hope it helps you !
