Examples Of Vinyl Groups

It consists of a methylene bridge ch 2 attached to a vinyl group ch ch 2.

Examples of vinyl groups. The molecules of two different compounds can also be made to link up forming a copolymer such as the plastic vinylite and the. An alkenyl group is a hydrocarbon group formed when a hydrogen atom is removed from an alkene group. It is the third most widely produced synthetic plastic variety in the world. Vinyl compounds contain the hydrocarbon vinyl group ch 2 ch.

In vinyl group c c is directly attached to the rest of the chain. That is to join end to end forming a polyvinyl compound such as polyvinyl chloride. One of the best examples of an industrial application of vinyl group is vinyl chloride ch 2 ch cl. The molecules of a single vinyl compound can be made to polymerize.

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. H 2 c ch ethenyl or commonly known as vinyl. 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. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms.

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. Vinyl indicates the ch ch 2 functional group which can be formed by removing hydrogen from ethylene. This is the main difference between allyl and vinyl groups. Unlike vinyl group the allylic carbon atom is sp 3 hybridized as it bonded with ch ch 2 through a single covalent bond.

In contrast to vinyl allyl group is attached to the rest of the molecule through ch 2 group. 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. Alkenyl compounds are named by replacing the e from the parent alkene s name with yl. An industrially important example is vinyl chloride precursor to pvc a plastic.

Functional groups are groups of atoms found within molecules that are involved in the chemical reactions characteristic of those molecules. 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.
