Atoms or groups attached to an allylic carbon are termed allylic substituents.
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.
