Allylic Vs Vinylic

Allyl compounds are of a wide range and are used in several areas.

Allylic vs vinylic.

The vinylic hydrogens are shown in red. Since both carbon atoms form a double covalent bond so both are sp 2 hybridized. Allyl chloride is used to produce plastics and used as an alkylating agent. Allylic carbon atom can form stable carbocations due to electron delocalization.

So the two carbons that participate in a double bond are vinylic and carbons attached to those are allylic. Benzylic position allylic position propargylic position aryl aryl hydrogen. Allylic compounds are precursors to many natural products including natural rubber and biosynthesis f terpenes. The allylic position is also like a vinylic position.

A hydrogen atom bonded to an sp 2 carbon of an alkene. Identify the number of allylic and vinylic hydrogens in the pictured molecules. 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. It is used as a precursor to manufacture polyvinyl chloride pvc.

Allyl group gets attached to any other group of atoms through ch 2 group whereas vinyl group is directly attached to any other group of atoms. None of the other hydrogens are vinylic. There s a distinction between an allylic vinyllic carbon and an allylic vynyllic group because allylic vynyllic groups are those that are attached to allylic vynyllic carbons. Vinylic compounds can produce vinylic polymers such as pvc pvf pvac etc.

The key difference between allylic and vinylic carbon is that allylic carbon is the carbon atom adjacent to the double bonded carbon atom whereas vinylic carbon atom is one of the two atoms that share the double bond. Allyl form a stable carbocation because of the electron delocalization whereas vinylic carbocations are unstable as they lack p character.
