cis-trans isomerism

noun

: geometric isomerism in unsaturated compounds or cyclic compounds depending usually on the presence in the molecule of a pair of substituted groups (as unsymmetrically substituted methylene groups) so that the isomers have comparable substituents on either the same or opposite sides of the molecule: such as

: stereoisomerism in compounds (as maleic and fumaric acids) containing one or more carbon-to-carbon double bonds

: syn-anti isomerism

: stereoisomerism in various cyclic compounds (as disubstituted cyclohexanes) which in many cases may also exhibit optical isomerism
