WebAre double bonds Stereocenters? The carbon atoms that form the C=C double bond in 2-butene are called stereocenters or stereogenic atoms. A stereocenter is an atom for which the interchange of two groups converts one stereoisomer into another. The carbon atoms in the C=C double bond in 2-butene, for example, are stereocenters. WebA chiral centre is an atom that has four different groups bonded to it in such a manner that it has a nonsuperimposable mirror image.
