But-2-ene is an acyclic alkene with four carbon atoms. It is the simplest alkene exhibiting cis/trans-isomerism (also known as (E/Z)-isomerism); that is, it exists as two geometric isomers cis-but-2-ene ((Z)-but-2-ene) and trans-but-2-ene ((E)-but-2-ene). It is a petrochemical, produced by the catalytic cracking of crude oil or the dimerization ...

2-Butene | C4H8 | CID 62695 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

All four butenes are gases at room temperature and pressure. …alkenes, two versions of 2-butene exist. They are traditionally called cis -2-butene and trans -2-butene or, in slightly more modern terms, (Z)- and (E)-2-butene. The Z and E stand for the German words for “together” (zusammen) and “apart” (entgegen).

2-butene is an unsaturated hydrocarbon with the molecular formula C4H8. It is an alkene with a carbon-carbon double bond located at the second carbon position of the four-carbon chain. This structural feature of 2-butene is central to understanding its behavior and properties in the context of various organic chemistry topics.

butene, any of four isomeric compounds belonging to the series of olefinic hydrocarbons. The chemical formula is C 4 H 8. The isomeric forms are 1-butene, cis - 2-butene, trans -2-butene, and isobutylene. All four butenes are gases at room temperature and pressure.
