(organic chemistry)
A compound of carbon and a halogen, sometimes with hydrogen.

Halocarbon

Class of man-made chemicals, including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs), whose heat-trapping properties are among the most damaging of the greenhouse gases. This, coupled with their tendency to remain in the atmosphere for hundreds of years, has resulted in limits on their use. Halocarbons are most commonly used in refrigeration, air conditioning, and electrical systems, as well as blowing agents in some foam insulation products.
