Naming Alkenes Vinyl

Draw the structure of a vinyl ethenyl and allyl 2 propenyl group and use these names in alkene nomenclature.

Naming alkenes vinyl.

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. Iupac rules for alkene and cycloalkene nomenclature 1. If the double bond is in the center of the chain. The ene suffix ending indicates an alkene or cycloalkene.

Give the iupac equivalent of the following trivial names. Alkadiene alkatriene etc or polyene for acyclic hydrocarbons with two or more double bonds. Ethylene propylene isobutylene and isoprene. An industrially important example is vinyl chloride precursor to pvc a plastic.

The longest chain chosen for the root name must include both carbon atoms of the double bond. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. Give the iupac equivalent of the following trivial names. However the iupac recommends using name alkene only for acyclic hydrocarbons with just one double bond.

Ethylene propylene isobutylene and isoprene. 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 structure of a vinyl ethenyl and allyl 2 propenyl group and use these names in alkene nomenclature.

In chemistry an alkene is a hydrocarbon that contains a carbon carbon double bond.
