Concept introduction:
Those compounds which have the same molecular formula but have different arrangements of atoms are known as isomers. The phenomenon is called isomerism. The isomers are generally classified as structural isomers and stereoisomers. Stereoisomers are further divided into two categories diastereomers and enantiomers. Enantiomers are the isomers which are non-superimposable mirror images of each other. Diastereomers are the isomers which are non-superimposable and are not mirror images of each other.

Concept introduction:
Fischer projections is a two dimensional representation of organic compounds. It was proposed to represent glucose molecules. The carbon chain is represented vertically; the hydoxy groups and hydrogen atoms are represented horizontally, according to their stereochemistry. The
