Allyl form a stable carbocation because of the electron delocalization whereas vinylic carbocations are unstable as they lack p character.
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.
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.
The key difference between allylic and vinylic carbon is that allylic carbon is the carbon.
It provides plenty of examples including allylic and vinyli.
Allyl group holds three carbon atoms and five hydrogen atoms on the other hand vinyl group has two carbon atoms and three hydrogen 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.
Since both carbon atoms form a double covalent bond so both are sp 2 hybridized.
An allylic carbon is a carbon atom bonded to a carbon atom that in turn is doubly bonded to another.
