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).

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).

Butene, also known as butylene, is an alkene with the formula C 4 H 8. The word butene may refer to any of the individual compounds. They are colourless gases that are present in crude oil as a minor constituent in quantities that are too small for viable extraction.
