Cis and trans isomers are
WebTraditionally, double bond stereochemistry was described as either cis (Latin, on this side) or trans (Latin, across), in reference to the relative position of substituents on either side of a double bond. A simple example of cis-trans isomerism is the 1,2-disubstituted ethenes, like the dichloroethene (C 2 H 2 Cl 2) isomers shown below. WebIn principle, cis - and trans -2-butene are conformational isomers; in theory, they could be interconverted by a simple rotation about the central double bond. However, the practical world intrudes into principle, because this rotation would require about 66 kcal/mol, an amount of energy not available under normal conditions.
