Lecture
This lecture covers the concept of enantiomers, a type of stereo isomer that are non-superimposable mirror images. It explains the different types of isomers, including constitutional and stereo isomers, and delves into the properties of chiral compounds. The lecture also discusses the rules to determine chirality in complex molecules, such as symmetry elements and improper rotation axes. Additionally, it explores the optical activity of chiral compounds and the phenomenon of racemic mixtures. The importance of enantiomers in chemistry and their role in stereoselective reactions are highlighted.
