WebOptical isomers have identical physical properties (except for polarised light) and identical chemical properties unless reacting with other optical isomers, when the orientation of the two molecules could have a bearing on the final result, for example in biological systems. WebAn optically active substance is one which can rotate the plane of polarisation of plane polarised light. if you shine a beam of polarised monochromatic light (light of only a single frequency - in other words a single colour) through a solution of an optically active substance, when the light emerges, its plane of polarisation is found to have …
WebWhen two enantiomers are present in equal proportions they are collectively referred to as a racemic mixture, a mixture that does not rotate polarized light because the optical activity of each enantiomer is cancelled by the other.

Esters Lab WebOptical isomerism A carbon atom that has four different atoms or groups of atoms attached to it is called a chiral carbon or chiral centre Compounds with a chiral centre ( chiral molecules) exist as two optical isomers which are also known as enantiomers
WebOptical isomerism is a type of stereoisomerism in which the isomers have the same molecular formula and the structural formula but differ in their direction of rotation of plane polarized light.
