CFC's - ChloroFluoroCarbons - are a class of volatile organic compounds that have been used as refrigerants, aerosol propellants, foam blowing agents, and as solvents in the electronic industry
ChloroFluroCarbon
a fluorocarbon with chlorine;
Commercially, the most important CFCs were derivatives of methane and ethane. These included trichlorofluoromethane (CFC-11), dichlorodifluoromethane (CFC-12), 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113) and 1,2-dichloro-1,1,2,2-tetrafluoroethane (CFC-114).
CFCs were first introduced in the 1930s as safe replacements for refrigerants such as sulfur dioxide, ammonia, chloroform, and carbon tetrachloride. These uses eventually resulted in large emissions of CFCs into the atmosphere.
Because of their low chemical reactivity, CFCs typically have long atmospheric residence times, and as a consequence are distributed globally. However, when CFCs reach the stratosphere they break down to release chlorine atoms. The chlorine atoms then react with stratospheric ozone, breaking it down into oxygen.
As ozone absorbs much of the sun's ultraviolet radiation, decreased stratosphere ozone levels could lead to increased ground-level ultraviolet radiation. This could adversely affect crop growth, and also lead to increases in cataracts and nonmelanoma skin cancer
CFCs are therefore now banned because they are the cause of the holes that grew in the Ozone layers over the planets polar regions.
The banning of CFCs has lead to research to identify other chemicals that can be used in the same applications but without the same environmental concerns.

Chlorofluorocarbon. It is an organic compound that includes carbon, fluorine and chlorine. It is used as refrigerants, in aerosol applications and solvents. CFC's contribute the the depletion of the ozone layer. 200 countries agreed to eliminate CFC's by 2020
Damage The Ozone Layer
Chloro Fluro Carbons breaks down the ozone layer into oxygen and therefore make holes in the ozone layer.
CFC molecules are refrigerants mainly. They are ozone depleting substances.
CFC's are in liquid form at first. But then they can convert into gaseous form.

CFC's stay for a long time. They deplete 100,000 molecules of ozone each.
Ozone hole is caused by CFC's. They are formed by air conditioners.
LPG - Liquid propane gas or other Hydrocarbon derivatives... Soft CFC's, they added hydrogen to the CFC's previously used that were called hard CFC's. By doing this it won't allow the CFC's to travel up to the stratosphere, where it breaks down the ozone. With the added hydrogen will stop it in the troposphere and combine to form compounds such as CO2 + HCl (or HF), therefore not harmful to the ozone. Examples CH2Cl (HCFC-22) or CHCl2-CF2 (HCFC-123)
Deodorants contain CFC's. they deplete ozone layer.
ChloroFluoroCarbon is the full form of CFC.
No. CFC's are a man made gas.

Yes. Tetrafluoroethane is a non-CFC gas. CFCs are chlorfluorocarbons which contain both chlorine and fluorine. Tetrafluoroethane does not contain chlorine.
CFC gas is used for cooling refrigerator.

CFC or chloroflourocarbon
CFC's stay for a long time. They deplete 100,000 molecules of ozone each.
no. it stands for Chloro Floro Carbon
No, SO2 is an inorganic acid gas made from sulphur and oxygen. A CFC is a chlorofluorocarbon made from fluorine, carbon and chlorine.
