Allyl compounds are of a wide range and are used in several areas.
Allylic vs vinylic. So the two carbons that participate in a double bond are vinylic and carbons attached to those are allylic. Allylic carbon atom can form stable carbocations due to electron delocalization. Benzylic position allylic position propargylic position aryl aryl hydrogen. 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.
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. Vinyl group vinylic hydrogen vinylic carbocation allylic position benzylic position propargylic position wikipedia entry return to glossary index. The vinylic hydrogens are shown in red.
Vinylic compounds can produce vinylic polymers such as pvc pvf pvac etc. It is used as a precursor to manufacture polyvinyl chloride pvc. Allylic compounds are precursors to many natural products including natural rubber and biosynthesis f terpenes. Identify the number of allylic and vinylic hydrogens in the pictured molecules.
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. Allyl chloride is used to produce plastics and used as an alkylating agent. The double bonded carbon atoms can be classified as vinylic and allylic carbon atoms.
The allylic position is also like a vinylic position. One of the best examples of an industrial application of vinyl group is vinyl chloride ch 2 ch cl.
