Halocarbons
Chemicals consisting of carbon, sometimes hydrogen, and either chlorine, fluorine bromine or iodine. (source: EPA) Background from Wikipedia Halocarbon compounds are chemicals in which one or more carbon atoms are linked by covalent bonds with one or more halogen atoms: fluorine, chlorine, bromine or iodine. There are also compounds such as methylammonium chloride that include carbon atoms and noncovalent halogen atoms, also called inorganic halogens. Unlike halocarbon halogens, noncovalent halogen atoms will usually dissociate and ionize in water. Halocarbons are a class of organic compounds containing covalently bonded fluorine, chlorine, bromine, or iodine.
