WebSep 13, 2024 · Cis-trans (geometric) isomerism exists when there is restricted rotation in a molecule and there are two nonidentical groups on each doubly bonded carbon atom. 12.3: Cis-Trans Isomers (Geometric Isomers) is shared under a CC BY-NC-SA license and was authored, remixed, and/or curated by LibreTexts. WebWhen atoms other than hydrogen are attached to the carbon atoms forming a double bond, and they lie on the same side of the double bond, the compound is referred to as a cis -isomer. When they lie on opposite sides of the bond, it is known as a trans -isomer.

WebIt is an important chemical method in which a chelating ligand with two donor atoms is allowed to react with cis - and trans -isomers separately. With cis -isomers, both the donor atoms of a chelating ligand coordinate to the central atom, forming a chelate with a five- or six-membered ring. WebIn many cases, the cis-trans isomers of a compound have different physical properties. These differences can arise due to the difference in the dipole moment of the …
