9.1 Names and Structures for Halogenated Compounds

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 – group 17) resulting in the formation of organofluorine compounds, organochlorine compounds, organobromine compounds, and organoiodine compounds. Chlorine halocarbons are the most common and are called organochlorides. WebHalogenated hydrocarbons are widely used as chemical intermediates, solvents, and pesticides. As a result, humans may be exposed to these chemicals through the environment as well as in the workplace. There are a number of toxic effects associated with acute and chronic exposure to halogenated hydrocarbons, including nephrotoxicity. hpa axis stands for https://beyondthebumpservices.com
