Question

Chlorofuorocarbons, or CFCs, consist of which of the following chemicals?

1) Chlorine, Fluorine, Carbon
2) Chlorine, Fluorine, Oxygen
3) Chlorine, Oxygen, Carbon
4) Fluorine, Oxygen, Carbon

Answer 1

CFCs are composed of chlorine, fluorine, and carbon. The correct chemical components making up CFCs corresponds to option 1) Chlorine, Fluorine, Carbon. CFCs have been largely phased out due to their harmful effects on the ozone layer.

Step-by-step explanation:

Chlorofluorocarbons, or CFCs, are chemical compounds made up of chlorine, fluorine, and carbon. This means that the correct answer to the question is 1) Chlorine, Fluorine, Carbon. CFCs are derived from hydrocarbons such as methane, ethane, and propane where some or all the hydrogen atoms have been replaced by chlorine and fluorine atoms.

Examples of CFCs include chlorofluorocarbon-11 (CFC-11), chlorofluorocarbon-12 (CFC-12), and many others that have been used in various applications such as refrigerants, solvents, and propellants in aerosol sprays. However, due to their damaging effects on the ozone layer, the use of CFCs has been largely phased out under international agreements like the Montreal Protocol, in favor of more environmentally friendly alternatives such as hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs).
