What is a vinyl group in organic chemistry?
A vinyl group is the smallest group that contains a vinylic carbon. An allyl group is the smallest group that contains an allylic carbon. The substituent is on the vinylic or allylic carbon.
What functional group is ch2?
Methylene group
In organic chemistry, a methylene group is any part of a molecule that consists of two hydrogen atoms bound to a carbon atom, which is connected to the remainder of the molecule by two single bonds. The group may be represented as CH2<, where the ‘<‘ denotes the two bonds.
What is allyl and vinyl?
Allyl and vinyl are two different organic functional groups. Both have C-C double bonds but in different positions. In vinyl group, C=C is directly attached to the rest of the chain. In contrast to vinyl, allyl group is attached to the rest of the molecule through –CH2 group.
What is a vinylic position?
Vinylic position: On, or bonded to, the carbon of an alkene. This molecule has four vinylic positions, each marked with *. Lewis structure of vinyl chloride, a vinylic halide. Related terms: Vinyl group, vinylic hydrogen, vinylic carbocation, allylic position, benzylic position, propargylic position.
What is meant by Vinyl group?
In chemistry, vinyl or ethenyl (abbreviated as Vi) is the functional group with the formula H-C=CH2. It is the ethylene (IUPAC 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.
Why is it called vinyl?
At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the name “vinyl”.
What functional group is CH?

What is a CH group called?
In chemistry, a methine group or methine bridge is a trivalent functional group =CH−, derived formally from methane. It consists of a carbon atom bound by two single bonds and one double bond, where one of the single bonds is to a hydrogen.
What is meant by vinyl group?
What are allyl groups?
An allyl group is a substituent with the structural formula H2C=CH−CH2R, where R is the rest of the molecule. It consists of a methylene bridge (−CH2−) attached to a vinyl group (−CH=CH2). The name is derived from the Latin word for garlic, Allium sativum.
Is Vinyl group electron donating?
Vinyl group is not electron donating.
