12. Stereochemistry - JEE Main - Core Revision Points

Importance of  Core Revision Points: Core Revision Points are important because if you remember them strongly, many more points related to them will come out of your memory and help you to answer question and problems. Read them many times and make sure you remember them very strongly.

Core Revision Points in Sections in the Chapter

12.1 Types of isomerism

Isomers are two types: constitutional (structural) and stereoisomers.

12.2 Geometrical isomerism
13.3 Confirmational isomerism
12.4 Optical activity



12.5 Chirality of objects and molecules
A chiral molecule is a molecule that is non superimposable on its mirror image.

12.6 Enantiomers
12.7 Configurations and Fisher Projections

12.8 Chiral or asymmetric carbon
The carbon atom which is bonded to four different groups or atoms is called chiral or asymmetric carbon.



12.9 Symmetry elements and chirality
12.10 Dissymetry – Condition for enantiomerism
12.11 Nomenclatures for stereo- isomers
12.12 Compounds containing two chiral centres

12.13 Meso compounds
Meso compound is a compound whose molecules are superimposable on their mirror images inspite of the presence of an assymmetric carbon atom. This is due to internal compensation.

12.14 Racemic mixtures and racemisation

12.15 Resolution
12.16 Importance of Stereo Chemistry
