Trans-pent-2-ene and cis-pent-2-ene are identical in constitution but different in configuration. This is the reason they are considered geometrical isomers of each other. ’Cis’ means both side groups are on the same side of the double bond, close to each other, as opposed to ’trans’, which means the atom groups are on opposite sides of the double bond.
Trans-pent-2-ene is a combustible chemical compound with a low boiling point and an unpleasant odor. It is a polymerization inhibitor. It participates in typical alkene reactions. Pentane is formed from its hydrogenation.
Occurrence and production
It can be found in natural gas and crack gases. It is produced from the dehydrogenation of pentane.
Trans-pent-2-ene is used for the production of certain organic compounds and to increase the octane number of petrol.
One of the isomers of pentene.
A colorless, heavier-than-air gas. Its geometric isomer is trans-2-butene.
A colorless, heavier-than-air gas. Its geometric isomer is cis-2-butene.
A liquid with a characteristic unpleasant odor and a low boiling point.
The fifth member in the alkane homologous series. A colorless, combustible liquid.
Member of the cycloalkane homologous series.
