WebOptical 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. WebThe natural phenomenon in which polarized light is rotated with the chiral molecules either in clockwise or anticlockwise direction is called optical activity. The intrinsic properties of light and the individual particles through which it passes are responsible for the rotation of the plane polarized light.
