| Summary | Optical activity is the ability of a chiral molecule to rotate the plane of polarized light, measured by a polarimeter. A chiral molecule (optically active) does not have any plane of symmetry or will produce a non-superimposable mirror image. If a molecule possesses any plane of symmetry or will produce supper imposable mirror image is to be treated as an achiral molecule (optically inactive). Non-superimposable mirror image is the essential condition for coordination compounds to become optically active (chiral). Optical isomers are capable to rotate plane-polarized light as right side or clockwise called dextrorotatory (d) and left side or anticlockwise called laevorotatory (l). An equilibrium mixture (1: 1) of d and l isomers that give a net-zero rotation is called a racemic mixture. Isomers are mirror images of each other and do not superimposable with each other (called enantiomers) and do not have a plane of symmetry, so they are called chiral compounds or optically active compounds. |
