Cis – trans isomers are stereoisomers, that is, pairs of molecules which have the same formula but whose functional groups are in different orientations in three-dimensional space. Cis-trans notation does not always correspond to E – Z isomerism, which is an absolute stereochemical description. See more Cis–trans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in chemistry that concerns the spatial arrangement of atoms within molecules. The prefixes "cis" and "trans" are from … See more Cis–trans isomerism can also occur in inorganic compounds, most notably in diazenes and coordination compounds. Diazenes Diazenes (and … See more • IUPAC definition of "stereoisomerism" • IUPAC definition of "geometric isomerism" • IUPAC definition of "cis–trans isomers" See more When the substituent groups are oriented in the same direction, the diastereomer is referred to as cis, whereas, when the substituents are oriented in opposing directions, the diastereomer is referred to as trans.

The origin of the cis and trans isomerism is the “locked” feature of the double. It locked because there is no rotation around the double bond and this, in turn, means that we cannot switch the orientation of the groups on the double bond. Recall that there is a free rotation about sigma bonds and ...
