Stereochemistry: Chirality, Enantiomers, and R/S Configuration

In this video, we introduce the fundamental concepts of stereochemistry, focusing on stereoisomerism and chirality. We begin by defining isomers and distinguishing between constitutional isomers and stereoisomers. Using both macroscopic objects and molecular examples, we explore the concept of chirality and what it means for an object to be non-superimposable on its mirror image. We then dive into molecular chirality, identifying chiral centers (carbons bonded to four different groups) and defining enantiomers. Finally, we apply the Cahn-Ingold-Prelog (CIP) system to assign priorities to substituent groups and determine the R or S configuration of chiral molecules.
