Introduction to Stereoisomerism and Optical Activity

Understanding how atoms connect and arrange themselves in three dimensions is fundamental to organic chemistry, explaining why molecules with the same formula can have vastly different properties. This course provides a clear, text-based foundation in isomerism, allowing you to confidently analyze molecular structure, predict chemical behavior, and interpret the crucial concept of chirality. What you'll learn: * Define and classify constitutional isomers, stereoisomers, and conformational isomers. * Master the Cahn-Ingold-Prelog priority rules for assigning R and S configurations to chiral centers. * Practice drawing and interpreting key three-dimensional molecular representations, including Fischer and Newman projections. * Apply the principles of optical activity to distinguish between enantiomers, diastereomers, and meso compounds. * Analyze the critical role of stereochemistry in modern drug design and biological processes. The course begins with foundational definitions and nomenclature before progressing through two-dimensional and three-dimensional structural analysis. You will work through detailed explanations and practice exercises focused on stereochemical conventions and optical activity. This course is designed for absolute beginners in organic chemistry or anyone needing a thorough review of isomerism. No prior chemistry knowledge beyond basic high school concepts is required.
