An allylic carbon is a carbon atom bonded to a carbon atom that in turn is doubly bonded to another.
Vinylic carbon vs allylic carbon.
Key difference allylic vs vinylic carbons functional groups are very important in understanding the different physical and chemical properties of organic molecules the terms allylic and vinyl carbons indicate whether the carbon atom is bonded directly or indirectly to a double bond in a molecule.
This organic chemistry video tutorial explains how to determine which carbocation is most stable.
The allylic carbon atom is more reactive than normal.
Allyl form a stable carbocation because of the electron delocalization whereas vinylic carbocations are unstable as they lack p character.
Since both carbon atoms form a double covalent bond so both are sp 2 hybridized.
The double bonded carbon atoms can be classified as vinylic and allylic carbon atoms.
The general formula for vinyl group is r ch ch 2 in which both carbon atoms are bonded with double bond and r is attached at vinylic position.
It provides plenty of examples including allylic and vinyli.
