Vinyl group
Vinyl group
The Vinyl group (pronounced: /ˈvaɪnɪl/), also known as ethenyl, is a type of functional group in organic chemistry. It is denoted by the formula -CH=CH2. The name "vinyl" is derived from "vinum", the Latin word for wine, because of its relationship with alcohol (ethanol).
Etymology
The term "vinyl" was first used in the year 1863 by the German chemist August Wilhelm von Hofmann. The term is derived from the Latin word "vinum" meaning wine, and "yl" a suffix used in organic chemistry to denote a group of atoms in a molecule.
Structure
The vinyl group consists of two carbon atoms double bonded together (C=C), with one hydrogen atom attached to each carbon. This structure is also known as an alkene group, which is a type of unsaturated hydrocarbon.
Properties
Vinyl groups are reactive, due to the presence of the carbon-carbon double bond. This reactivity allows them to participate in a variety of chemical reactions, including polymerization to form polyvinyl chloride (PVC) and other vinyl polymers.
