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. WebNov 17, 2024 · Cis-trans can occur whenever both double-bond carbons are directly attached to a carbon and a hydrogen. In this case, interchanging the substituents on one of the double-bond carbons creates a different isomer. If one of the double-bond carbons of an alkene is attached to two identical groups, cis-trans isomerism is not possible. WebCis,trans-isomerism can also occur in cycloalkanes, where free rotation about a carbon–carbon single bond is restricted. In a compound lacking a hydrogen atom on one … flower pictures images free
