Web30 nov. 2024 · The carbon atoms that form the C=C double bond in 2-butene are called stereocenters or stereogenic atoms. A stereocenter is an atom around which the interchange of two groups converts one stereoisomer into another. The carbon atoms in the C=C double bond in 2-butene are the stereocenters. 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).
