WebThe top pair is an example of the cis/trans (or E/Z if you want to use the strict UIPAC names) isomers in alkenes. The second pair also represents as cis/trans pair of isomers. Neither of molecules, however, have chiral atoms. And since each pair represents a couple of non-superimposable molecules that are not mirror images, they are diastereomers. 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. An example of a small hydrocarbon displaying cis–trans isomerism is but-2-ene. Alicyclic compounds can also display cis–trans isomerism. As an example of a geometric isome…
