What does CFC stand for?

• A. ChloroFluorCompounds
• B. ChloroFluoroCompounds
• C. Chlorinated Fluorocarbons
• D. ChloroFluorocarbons

Answer: (D)

The term CFC stands for ChloroFluorocarbons, which is the correct choice. CFCs are a class of compounds that contain chlorine, fluorine, carbon, and hydrogen. They were commonly used as refrigerants, aerosol propellants, and solvents before their harmful effects on the ozone layer were fully understood.

CFCs are known for their stability in the lower atmosphere, which allows them to eventually reach the stratosphere where they can be broken down by ultraviolet radiation, releasing chlorine atoms that contribute to ozone depletion. The recognition of this environmental impact led to international agreements, such as the Montreal Protocol, aimed at phasing out the production and consumption of CFCs.

In contrast, the other options either mislabel the compounds by including incorrect combinations of terms or chemical features. Understanding the terminology surrounding CFCs is vital for comprehending their role in environmental science and regulations concerning refrigerants and other chemicals.
