What Is A Vinyl Halide

In alkyl halides all four bonds to the carbon that bears the halogen are single bonds.

What is a vinyl halide.

Vinyl chloride is one such substance. In organic chemistry a vinyl halide is a compound with the formula ch 2 chx x halide the term vinyl is often used to describe any alkenyl group. In organic chemistry a vinyl halide is any alkene with at least one halide substituent bonded directly on one of the unsaturated carbons. Vinyl halide is a hydrocarbon in which the halogen x cl i f br is directly attached to a alpha carbon sp2.

The simplest example would be 1 halo eth 1 ene. They are subdivided into alkyl vinylic aryl and acyl halides. The extra strength of the carbon halogen bond in aryl halides. These include conversion to vinyl grignard reagents elimination to give the corresponding alkyne and.

From the perspective of applications the dominant member of this class of compounds is vinyl chloride which is produced on the scale of millions of. Aryl halides or haloarenes. A general vinyl halide could be represented as where ri is a alkyl group or any ot. There is an interaction between one of the lone pairs on the chlorine atom and the delocalized ring electrons and this strengthens the bond.

Other articles where geminal dihalide is discussed. In aryl halides the halogen bearing carbon is part of. Key difference allyl vs vinyl both allyl and vinyl groups have slightly similar structures with a small variation. A vinyl halide is clearly a species with a formula h 2c c x h in which a halide is directly bound to an olefinic bond formally this is ethylene h 2c ch 2 with one of the hydrogens substituted by a heteroatom vinyl chloride h 2c chcl is an example.

Treatment of a geminal dihalide both halogens on the same carbon or a vicinal dihalide halogens on adjacent carbons with a base such as sodium ethoxide naoch2ch3 yields a vinylic halide. Vinyl chloride is a colorless gas that burns easily. What is vinyl chloride. In vinyl halides the halogen atom is bonded to an sp 2 hybridised carbon atom of c c double bond.

Dehydrohalogenation of a dihalide. Allyl groups have three carbon atoms and five hydrogen atoms. In aryl halides the halogen atom is directly bonded to an sp 2 hybridised carbon of benzene. An aryl halide has general formula c 6h 5x in which an halide group x has substituted the aryl ring.

Vinyl chloride is used primarily to make polyvinyl chloride pvc. In vinylic halides the carbon that bears the halogen is doubly bonded to another carbon. Other articles where vinylic halide is discussed. For this reason alkenyl halides with the formula rch chx are sometimes called vinyl halides.

Vinyl halides are very useful synthetic intermediates due to the vast number of reactions that make use of them. The carbon chlorine bond in chlorobenzene is stronger than you might expect. The key difference between these two structural components is the number of carbon and hydrogen atoms.
