What does CFC stand for?

• A. Chlorosubstituted hydrocarbon
• B. Chlorofluorocarbon
• C. Carbon fluorine compound
• D. Chloride fluorine carbon

Answer: (B)

CFC stands for Chlorofluorocarbon. This term specifically refers to a class of chemicals that have been widely used as refrigerants, propellants in aerosol sprays, and solvents. Chlorofluorocarbons contain chlorine, fluorine, carbon, and hydrogen. Their significance arises from their role in ozone layer depletion, as they break down in the atmosphere and release chlorine atoms that destroy ozone molecules. Understanding what CFC means is vital in the context of environmental regulations and the need to phase out substances that harm the ozone layer.

The other terms do not accurately define CFCs. For example, chlorosubstituted hydrocarbons could refer to a broader class of compounds that might include CFCs but does not specify the fluorine component essential to define CFCs properly. Carbon fluorine compound implies a structure without the necessary mention of chlorine, which is critical for CFC classification. Chloride fluorine carbon mixes terms and does not conform to recognized chemical naming conventions. Thus, Chlorofluorocarbon is the precise term that encapsulates the characteristics of CFCs.
