Allylic And Vinylic Hydrogens

Allyl form a stable carbocation because of the electron delocalization whereas vinylic carbocations are unstable as they lack p character. 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. In other words it is a methylene bridge ch 2 attached to a vinyl group ch ch 2.
