Chemical structure of the vinyl functional group.

In organic chemistry, a vinyl group (abbr. Vi;[1] IUPAC name: ethenyl group[2]) is a functional group with the formula −CH=CH2. 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−CH=CH2 where R is any other group of atoms.

An industrially important example is vinyl chloride, precursor to PVC,[3] a plastic commonly known as vinyl.

Chessboard made from polyvinyl chloride

Vinyl is one of the alkenyl functional groups. On a carbon skeleton, sp2-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.)
