In organic chemistry, a vinyl group (abbr. Vi; IUPAC name: ethenyl group) is a functional group with the formula −CH=CH 2. It is the ethylene (IUPAC name: ethene) molecule ( H 2 C=CH 2 ) with one fewer hydrogen atom.
Vinyl or ethenyl is the functional group C H = C H 2, namely the ethylene molecule (H 2 C = C H 2) minus one hydrogen atom. The name is also used for any compound containing that group, namely R C H = C H 2 where R is any other group of atoms.
Sep 24, 2023 · A vinyl group is a functional group with the formula $\ce{−CH=CH2}$ and allyl group is vinyl group but an extra methylene bridge ($\ce{-CH2}$), so it is $\ce{−CH2−HC=CH2}$. So, the carbons in vinyl group is "vinylic" carbon and the carbon in the extra methylene bridge is the "allylic" carbon.
The general formula for vinyl group is R-CH=CH 2 in which both carbon atoms are bonded with a double bond and R is attached at vinylic position. Since both carbon atoms form a double covalent bond so both are sp 2 hybridized.
A vinyl group is an alkene with the formula CH₂=CH−, where two carbon atoms are double-bonded to each other, and one of these carbons is bonded to another group or element. It acts as a fundamental unit in organic chemistry for forming more complex molecules through reactions at its double bond.
Vinyl compounds contain the hydrocarbon vinyl group (CH 2 =CH-). The molecules of a single vinyl compound can be made to polymerize; that is, to join end to end, forming a polyvinyl compound such as polyvinyl chloride.
Over the last 50 years, Vinyl Products has flourished into a diversified conglomerate – The Vinyl Group of Companies – encompassing a diverse range of ventures including manufacturing, trading, finance, retail, and hospitality.
Vinyl group: A portion of a molecular structure equivalent to ethylene minus one hydrogen atom.
What is a Vinyl Group? Vinyl group is the name given to the functional group of -CH=CH 2. It can be seen as an ethene molecule with one less hydrogen in number. Hence it is also called as ethenyl group at times.
The vinyl group (CH 2 =CH–) and derivatives formed by substitution. Informally, a group, such as –OH, attached to the free valence of a (substituted) vinyl group is sometimes referred to as 'vinylic'.
