(c) Stereochemical aspects of nucleophilic substitution reactions
In order to understand the stereochemical aspects of substitution
reactions, we need to learn some basic stereochemical principles
and notations (optical activity, chirality, retention, inversion,
racemisation, etc ) (i) Optical activity: Plane of plane polarised light produced by
passing ordinary light through Nicol prism is rotated when it
is passed through the solutions of  certain compounds Such
compounds are called optically active compounds
