WebSTEREOISOMERISM - GEOMETRIC ISOMERISM Geometric isomerism (also known as cis-trans isomerism or E-Z isomerism) is a form of stereoisomerism. This page explains what stereoisomers are and how you recognise the possibility of geometric isomers in a molecule. Further down the page, you will find a link to a second page which describes … WebStereoisomers occur when the ligands have the same bond, but the bonds are in different orientations relative to one another. In cis molecules, the two ligands are on the same side of the complex. In trans molecules, the similar ligands are on the opposite sides of the molecules. ...

WebJul 25, 2024 · Cis- isomers tend to have higher boiling points than their trans- counterparts. Trans- isomers generally have lower melting points and have lower densities than their cis- counterparts. Cis- isomers collect the charge on one side of the molecule, giving the molecule an overall polar effect. WebMar 26, 2016 · Consider the case of 2-pentene, shown here. In this alkene, two stereoisomers are possible.
