WebThe carbon and hydrogen atoms make up the key structural difference between allyl and vinyl groups. Both groups have similar structures with small variations. Vinyl carbon is an atom that shares a double bond with the carbon atom next to it, whereas allylic carbon is the atom next to the double-bonded carbon atom.
