Vinyl group

Vinyl group is a type of functional group in organic chemistry. It is derived from ethylene and consists of an alkene with the formula −CH=CH2. The name "vinyl" was coined from the alcohol in ethylene, called "vinyl alcohol", which was shortened to "vinyl".

Structure and bonding

The vinyl group is a type of alkene where the double bond is at the end of the chain. It is a derivative of ethylene, the simplest alkene. The carbon-carbon double bond in vinyl groups is highly reactive due to its pi bond. This reactivity is due to the fact that the pi bond electrons are loosely held and can easily participate in reactions.

Reactions

Vinyl groups can participate in a variety of reactions, including addition reactions, polymerization, and hydrogenation. In addition reactions, a molecule adds to the carbon-carbon double bond, resulting in a single bond and a more complex molecule. In polymerization reactions, vinyl groups can link together to form long chains, creating polyvinyl chloride (PVC) and other polymers. In hydrogenation reactions, the double bond of the vinyl group can be reduced to a single bond, creating ethyl.

Uses

Vinyl groups are commonly used in the production of polyvinyl chloride (PVC), a widely used plastic. They are also used in the production of many other polymers, including polyvinyl acetate (PVA), polyvinyl alcohol (PVOH), and polyvinyl butyral (PVB).
