A vinyl compound (formula −CH=CH2) is any organic compound that contains a vinyl group (Preferred IUPAC name ethenyl), which are derivatives of ethene, CH2=CH2, with one hydrogen atom replaced with some other group. An industrially important example is vinyl chloride, precursor to PVC, a plastic commonly known as "vinyl".
Vinyl groups are alkene derivatives: Primary alkenes contain vinyl 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).
The etymology of vinyl is the Latin vinum = "wine", because of its relationship with alcohol (in its original sense of ethyl alcohol).
Related to vinyl compounds are vinylidenes. Vinylidene itself, a rare species of theoretical interest, is a modified carbene with the formula CH2=C:. Vinylidenes describe compounds containing the functional group CX2=C. For example, 1,1-dichloroethene (CH2=CCl2) is called vinylidene chloride.
