In chemistry, vinyl or ethenyl〔 IUPAC Provisional Recommendations 2004 (Chapter 5 ) 〕 is the functional group −CH=CH2, namely the ethylene molecule (H2C=CH2) minus one hydrogen atom. The name is also used for any compound containing that group, namely R−CH=CH2 where R is any other group of atoms. An industrially important example is vinyl chloride, precursor to PVC, a plastic commonly known as ''vinyl''. Vinyl is one of the alkenyl functional groups. On a carbon skeleton, ''sp''2-hybridized carbons or positions are often called vinylic. Allyls, acrylates and styrenics contain vinyl groups. (A styrenic crosslinker with two vinyl groups is called ''divinyl benzene''.) ==Etymology== The etymology of ''vinyl'' is the Latin ''vinum'' = "wine", because of its relationship with alcohol (in its original sense of ethyl alcohol). The term "vinyl" was coined by the German chemist Hermann Kolbe in 1851.〔H.
