When one hydrogen atom is removed from the third carbon atom of a propane molecule it is equivalent to an allyl group.
An allylic carbon is an sp3 carbon that is adjacent to a vinylic 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.
Atoms or groups attached to an allylic carbon are termed allylic substituents.
None of the other hydrogens are vinylic.
