Exam-focused revision notes on Stereochemistry for CSIR-NET Chemical Sciences, GATE Chemistry and IIT-JAM — the core concepts, the formulas worth memorising, the traps that cost marks, and a quick-recall table.

The core idea

Stereoisomers have the same connectivity (same bonds, same molecular formula) but differ in the arrangement of atoms in space. They split into two families: enantiomers (non-superimposable mirror images) and diastereomers (stereoisomers that are not mirror images).
