Introduction to Optical Isomerism

This lesson teaches you how to identify and then further classify optically active substances into dextrorotatory and laevorotatory. It also discusses how to make such compounds. It's an important lesson from exam point of view and a must watch!

Dextro and laevorotatory substances

This lesson explains how optically active substances can differ in the nature of rotation. It also gives an important relation between the angle of rotation and the concentration of optically active substances. It's an important lesson from exam point of view and a must watch!

Nature of rotation

This lesson deals with the differentiation between chiral and achiral molecules. It also deals with the different elements of symmetry and how they affect the chirality in the molecule and finally, it's optical activity. It's an important lesson from exam point of view and a must watch!

Cause of optical activity

This lesson explains about the difference between asymmetric and dissymmetric molecules. It also discusses in detail about the plane of symmetry with examples. It's an important lesson from exam point of view and a must watch!

Afiya Shoaib

This course is about Isomerism and its various types. Each type has been discussed in detail. Various lessons have been created in regard of the same. In the later lectures, various questions have also been solved based on the concept of isomerism. These questions are basically chosen from the book 'Advanced Organic Chemistry by M.S. Chauhan'.
