WebIn organic chemistry, cis/trans isomerism is a form of stereoisomerism describing the relative orientation of functional groups within a molecule. It is not to be confused with … 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. [7]
