Chlorine gas is commonly used in the production of which of the following industrial compounds?

Chlorofluorocarbons are compounds containing chlorine, fluorine, and carbon atoms. Chlorine gas provides the chlorine atoms needed to make these molecules in chemical factories.

CFCs were once widely used in refrigerators, air conditioners, and spray cans. Scientists later discovered that CFCs damage the ozone layer, so their production is now restricted.

The production of CFCs requires reacting chlorine with fluorocarbons. Chlorine gas is the essential starting material that provides chlorine atoms for these industrial chemicals.
