WitrynaOptical isomerism is basically a type of stereoisomerism. Now, before we learn about optical isomerism let us quickly recall what are isomers and stereoisomers. Isomers are those compounds which have the same molecular formula but different bonding arrangement among atoms. Whereas, in stereoisomer, both molecular formula and …

WitrynaWhen it comes to optical isomerism, isomers are referred to as enantiomers. Four divisions are distinguished in the study of structural isomerism. i) Coordination Isomerism:- In this sort of isomerism, the exchange of ligands between the anionic and cationic species takes place between the two species. For example, interchangeability … WitrynaOptical isomerism . Optical isomerism occurs when the mirror image of a compound is not superimposable with the original compound. It is so called because such isomers are optically active, that is, they rotate the plane of polarized light.The symbol Λ (lambda) is used as a prefix to describe the left-handed propeller twist formed by three bidentate …

WitrynaGeometric 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 the E-Z notation for naming geometric isomers.
