What is freon?

उत्तर १
The chloro fluoro derivatives of methane and ethane are called freons.
Freon is represented as Freon – cba
Where, c = number of carbon atoms, b = number of hydrogen atoms, a = total number of fluorine atoms.
CF2Cl2 = 0
C = 1 – 1 = 0
H = 0 +1 = 1
F = 2
So Freon – 12 is CF2Cl2
उत्तर २
Freon refers to a group of chlorofluorocarbon (CFC) compounds, specifically refrigerants such as dichlorodifluoromethane (CCl2F2), which are widely used in refrigeration, air conditioning, and as aerosol propellants; however, Freon and similar CFCs are known to deplete the ozone layer in the stratosphere due to their chlorine content, which catalyzes the breakdown of ozone molecules. They are chemically stable, non-flammable, and efficient refrigerants but have environmental impacts related to ozone depletion.
