Vinyl Group Vs Allyl Group

Key difference allyl vs vinyl both allyl and vinyl groups have slightly similar structures with a small variation.

Vinyl group vs allyl group.

An allyl derivative was first found within the garlic oil by theodor wertheim in 1844 he named it schwefelallyl. An allyl group is a substituent with the structural formula h 2 c ch ch 2 r where r is. It consists of a methylene bridge ch 2 attached to a vinyl group ch ch 2. Isomerization to the more labile enol ether employing ko t bu with subsequent mild acidic hydrolysis is one of the most common deprotection methods.

An allyl group is a substituent with the structural formula h 2 c ch ch 2 r where r is the rest of the molecule. An industrially important example is vinyl chloride precursor to pvc a plastic. Allyl group definition the univalent group c3h5 derived from propylene. Alkoxy group alkyl group allyl group amino group benzoyl group benzyl group butyl group carbonyl group carboxyl group deactivating group.

In chemistry vinyl or ethenyl abbreviated as vi is the functional group with the formula c h ch 2 it is the ethylene iupac ethene molecule h 2 c ch 2 with one fewer hydrogen atom. Allyl group consists of ch 2 methylene bridge and is attached with ch ch 2 vinyl group. Allyl group holds three carbon atoms and five hydrogen atoms which gets attached to any other group of atoms through ch 2 group. The key difference between these two structural components is the number of carbon and hydrogen atoms.

A portion of a molecular structure equivalent to ethylene minus one hydrogen atom. Allyl groups have three carbon atoms and five hydrogen atoms. The allylic carbon atom is more reactive than normal. Both groups own a double bond between two carbon atoms where all the other atoms are bonded through single bonds.

The allyl group is a commonly used protecting group for alcohols with relative stability towards both acidic and basic conditions that permits orthogonal protection strategies. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. Allylic carbocations carbocation with a vinyl group as a substituent next to a double bond cc c 221 allyl carbocations are stabilized by. Allyl indicates a functional group with structural formula h 2 c ch ch 2 r where r is the rest of the molecule it consists of methylene bridge ch 2 in between the vinyl group ch ch 2 and the rest of the molecule therefore allyl group contains sp 2 hybridized vinyl carbon atoms and sp 3 hybridized allyl carbon atom.
