WebAug 6, 2024 · The isomer with the two Cl atoms on opposite sides of the molecule is the trans isomer (Latin trans, meaning “across”) and is named trans-1,2-dichloroethene. These two compounds are cis-trans isomers (or geometric isomers), compounds that have different configurations (groups permanently in different places in space) because … WebJun 12, 2016 · You draw stereochemical formulas of the isomers and look for superimposable mirror images. A molecule must have restricted rotation — a ring or a double bond — in order to have cis and trans isomers. Pentane-2,3-diol has neither a ring nor a double bond, so it has no cis or trans isomers. Here are the Fischer projections of …
