It is the ethylene (IUPAC name: ethene) molecule ( H2C=CH2) with one fewer hydrogen atom. The name is also used for any compound containing that group, namely R− ...
Vinyl chloride is an organochloride with the formula H 2 C = CHCl. It is also called vinyl chloride monomer ( VCM) or chloroethene. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). Vinyl chloride monomer is among the top twenty largest petrochemicals ( petroleum -derived ...
