Steric Arrangement in Cis and Trans Configuration

Web1,2-disubstituted alkenes are described as: cis - if the two alkyl groups, R-, are on the same side of the C=C. trans - if the two alkyl groups, R-, are on opposite sides of the C=C. these terms are inserted into the name as prefixes. cis-. trans-. For example, but-2-ene, where both R = methyl : Bei einer Doppelbindung lassen sich die cis- und trans-Isomere ineinander umwandeln (cis-trans-Interkonversion). Hierzu ist eine vorübergehende Auflösung der π-Bindung nötig, was meist photochemisch oder bei höheren Temperaturen erfolgt. Der Prozess der photochemischen Interkonversion erfolgt hierbei anhand elektronischer Anregung in den Singulett Spinzustand.
