Allylic Carbon Vs Vinylic. 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. Vinyl group has two carbon atoms and three hydrogen atoms. Both groups own a double bond between two carbon atoms where all the other atoms are bonded through single bonds.
Allyl group holds three carbon atoms and five hydrogen atoms. Allyl form a stable carbocation because of the electron delocalization.
Vinylic carbocations are unstable as they lack p character.
Allyl form a stable carbocation because of the electron delocalization. čo je to vinylic carbon 4. Since both carbon atoms form a double covalent bond so both are sp 2 hybridized. Vinylic carbocations are unstable as they lack p character.
