Explanation:

Freon is  stable, nonflammable, low toxicity gases or liquids which have generally been used as refrigerants and as aerosol propellants. These include the chlorofluorocarbons (CFCs) that cause ozone depletion and HCFCs (such as chlorodifluoromethane). Not all refrigerants of this type are labelled as "Freon" since Freon is a brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503 manufactured by The Chemours Company. The term "freon" is a common descriptor or proprietary eponym (similar to a generic trademark) like "xerox" or "kleenex." It is commonly used when referring to any fluorocarbon refrigerants.
