Vinylic Carbon Structure

General vinylic carbocation structure.

Vinylic carbon structure.

This molecule has four vinyl ic positions each marked with. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. The double bonded carbon atoms can be classified as vinylic and allylic carbon atoms. In chemistry vinyl or ethenyl abbreviated as vi is the functional group with the formula c h ch 2 it is the ethylene iupac ethene molecule h 2 c ch 2 with one fewer hydrogen atom.

The vinyl cation is a carbocation with the positive charge on an alkene carbon. A carbocation in which the carbon atom having the open octet and positive formal charge is part of a carbon carbon double bond. The carbocation carbon has sp hybridization. Since both carbon atoms form a double covalent bond so both are sp 2 hybridized.

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. For example the following compounds have all been isolated from the volatile oil of chondrococcus hornemanni a red seaweed found in the pacific ocean. It contains two sp 2 hybridized carbon atoms and one sp 3 hybridized carbon atom. A vinylic carbocation which has an empirical formula of c h is a carbocation that has a positive charge only on the alkene carbon atom.

An industrially important example is vinyl chloride precursor to pvc a plastic. On or bonded to the carbon of an alkene. Vinylic chlorides and bromides constitute a diverse class of marine natural products. Lewis structure of vinyl chloride a vinyl ic halide.

When one hydrogen atom is removed from the third carbon atom of a propane molecule it is equivalent to an allyl group. Any trivalent disubstituted carbon is generally a vinylic carbocation in which the carbon atom which is bearing the positive charge is found to be double bonded and will always exist as sp hybridized. Vinylic halides natural occurrence. 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.

The key difference between allylic and vinylic carbon is that allylic carbon is the carbon.
