Naming Alkenes Vinyl

If the double bond is in the center of the chain.

Naming alkenes vinyl.

An industrially important example is vinyl chloride precursor to pvc a plastic. Ethylene propylene isobutylene and isoprene. Ethylene propylene isobutylene and isoprene. Alkadiene alkatriene etc or polyene for acyclic hydrocarbons with two or more double bonds.

The longest chain chosen for the root name must include both carbon atoms of the double bond. Draw the structure of a vinyl ethenyl and allyl 2 propenyl group and use these names in alkene nomenclature. Give the iupac equivalent of the following trivial names. The ene suffix ending indicates an alkene or cycloalkene.

The term is often used as synonym of olefin that is any hydrocarbon containing one or more double bonds. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. 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 kekulé condensed or shorthand structure of an alkene cyclic or acyclic given its iupac name. The root chain must be numbered from the end nearest a double bond carbon atom. 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.

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.
