Examples Of Vinyl Groups

An industrially important example is vinyl chloride precursor to pvc a plastic.

Examples of vinyl groups.

It is the third most widely produced synthetic plastic variety in the world. That is to join end to end forming a polyvinyl compound such as polyvinyl chloride. An electron donating group edg or electron releasing group erg z in structural formulas is an atom or functional group that donates some of its electron density into a. This is the main difference between allyl and vinyl groups.

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 molecules of a single vinyl compound can be made to polymerize. Unlike vinyl group the allylic carbon atom is sp 3 hybridized as it bonded with ch ch 2 through a single covalent bond. An allyl group is a substituent with the structural formula h 2 c ch ch 2 r where r is the rest of the molecule.

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. In vinyl group c c is directly attached to the rest of the chain. Alkenyl compounds are named by replacing the e from the parent alkene s name with yl. It is used as a precursor to manufacture polyvinyl chloride pvc.

An alkenyl group is a hydrocarbon group formed when a hydrogen atom is removed from an alkene group. Vinyl indicates the ch ch 2 functional group which can be formed by removing hydrogen from ethylene. It consists of a methylene bridge ch 2 attached to a vinyl group ch ch 2. Functional groups can pertain to any molecules but you will usually hear about them in the context of organic chemistry the symbol r and r refer to an attached hydrogen or hydrocarbon side chain or sometimes to any group of atoms.

It imparts unique chemical properties to allylic group and presence of this group in different compounds form allylic compounds which are used for the preparation of different natural products like natural rubber terpenes etc. One of the best examples of an industrial application of vinyl group is vinyl chloride ch 2 ch cl. In an electrophilic aromatic substitution reaction existing substituent groups on the aromatic ring influence the overall reaction rate or have a directing effect on positional isomer of the products that are formed. Vinyl compounds contain the hydrocarbon vinyl group ch 2 ch.

In contrast to vinyl allyl group is attached to the rest of the molecule through ch 2 group. The name is derived from the latin word for garlic allium sativum in 1844 theodor wertheim isolated an allyl derivative from garlic oil and named it schwefelallyl.
