organohalogen compound
Vinyl chloride is an organohalogen compound that has important industrial applications. When treated with certain catalysts, vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride, or PVC. PVC is used in the manufacture of numerous products, including packaging films and water pipes.
In functional-class nomenclature, alkyl halides are named using two separate words. The first word is the IUPAC name of the alkyl group, and the second word is fluoride, chloride, bromide, or iodide, depending on the specific halogen present in the compound.1
When determining the name of the alkyl group, the chain is numbered starting at the carbon atom to which the halogen is directly attached. This system is distinct from substitutive nomenclature, which uses prefixes such as fluoro- or chloro- added to the name of the hydrocarbon framework.1
