Allylic Vs Vinylic

The vinylic hydrogens are shown in red.

Allylic vs 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. Allyl form a stable carbocation because of the electron delocalization whereas vinylic carbocations are unstable as they lack p character. Allyl chloride is used to produce plastics and used as an alkylating agent. Vinyl group vinylic hydrogen vinylic carbocation allylic position benzylic position propargylic position wikipedia entry return to glossary index.

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. A hydrogen atom bonded to an sp 2 carbon of an alkene. 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.

Vinylic compounds can produce vinylic polymers such as pvc pvf pvac etc. Allylic carbon atom can form stable carbocations due to electron delocalization. Identify the number of allylic and vinylic hydrogens in the pictured molecules. None of the other hydrogens are vinylic.

Allylic compounds are precursors to many natural products including natural rubber and biosynthesis f terpenes. The double bonded carbon atoms can be classified as vinylic and allylic carbon atoms. The allylic position is also like a vinylic position. Since both carbon atoms form a double covalent bond so both are sp 2 hybridized.

So the two carbons that participate in a double bond are vinylic and carbons attached to those are allylic. Allyl compounds are of a wide range and are used in several areas.
