Chlorofluorocarbons are compounds consisting of which elements?

Chlorofluorocarbons (CFCs) are synthetic compounds notable for their use as refrigerants and propellants in aerosol sprays. The correct choice accurately identifies the essential elements that make up chlorofluorocarbons: chlorine, fluorine, carbon, and hydrogen.

CFCs typically consist of carbon atoms bonded to halogen atoms, which in this case are chlorine and fluorine, alongside hydrogen atoms. This combination contributes to their unique chemical properties, such as stability in the lower atmosphere and volatility, but they have a significant environmental impact, particularly in ozone depletion.

Understanding the specific elemental composition is critical for discussions about environmental science, particularly due to CFCs' involvement in global warming and ozone layer degradation. While other elements mentioned in the other options might be found in different compounds, they do not form chlorofluorocarbons. The identification of the correct elements is essential for understanding the behavior and risks associated with these chemicals.
