"WebGeometric isomers are stereoisomers that differ in the arrangement of atoms around a double bond or ring structure. The two most common types of geometric isomers are cis-isomers and trans-isomers. In a cis-isomer, the functional groups or substituents are on the same side of the molecule, while in a trans- isomer, they are on opposite sides. " - Cis-isomerism

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.
