Naming Alkenes Vinyl

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 root chain must be numbered from the end nearest a double bond carbon atom. H2c ch vinyl group h2c ch ch2 allyl group rule 1 alkenes are named using the same general naming rules for alkanes except that the suffix is now ene.

Give the iupac equivalent of the following trivial names.

Naming alkenes vinyl.

The longest chain chosen for the root name must include both carbon atoms of the double bond. An industrially important example is vinyl chloride precursor to pvc a plastic. Draw the structure of a vinyl ethenyl and allyl 2 propenyl group and use these names in alkene nomenclature. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms.

Draw the kekulé condensed or shorthand structure of an alkene cyclic or acyclic given its iupac name. Give the iupac equivalent of the following trivial names. Iupac rules for alkene and cycloalkene nomenclature 1. Ethylene propylene isobutylene and isoprene.

In chemistry an alkene is a hydrocarbon that contains a carbon carbon double bond. However the iupac recommends using name alkene only for acyclic hydrocarbons with just one double bond. Draw the structure of a vinyl ethenyl and allyl 2 propenyl group and use these names in alkene nomenclature. The term is often used as synonym of olefin that is any hydrocarbon containing one or more double bonds.

Draw the kekulé condensed or shorthand structure of an alkene cyclic or acyclic given its iupac name. The ene suffix ending indicates an alkene or cycloalkene. If the double bond is in the center of the chain. Alkadiene alkatriene etc or polyene for acyclic hydrocarbons with two or more double bonds.

Ethylene propylene isobutylene and isoprene.
