Basics on stereochemistry

Delve into the fascinating world of stereochemistry! This course provides a comprehensive exploration of molecular shapes and their properties, crucial for understanding chemistry, biology, and pharmaceuticals.

Here's what you'll learn:

• Fundamentals of Stereochemistry: Begin with a historical overview and essential definitions, laying the groundwork for understanding the intricacies of molecular stereoisomers.
• Isomer Classification: Master the classification of isomers, a fundamental concept in organic chemistry.
• Conformations: Explore different molecular conformations and their characteristics.
• Stereoisomers in Detail: A deep dive into stereoisomers, including:
  • Geometrical Isomers: Learn to identify and differentiate geometrical isomers with illustrative examples.
  • Optical Isomers: Understand optical isomers and optical activity, with practical examples. Distinguish between enantiomers and diastereomers.
  • Chiral vs. Achiral Molecules: Develop the ability to differentiate between chiral and achiral molecules.
• Visualizing Molecular Shape: Gain proficiency in visualizing molecules, including:
  • Chirality Visualization: Understand and visualize chiral and achiral objects.
  • Symmetry Elements: Explore symmetry elements in molecules, contrasting rotation axes and mirror planes.
• Plane Polarized Light: Introduction to plane polarized light and its role in identifying chiral substances.
• Understanding Chirality: Learn to define chirality in terms of "handedness" and the concept of mirror image superimposability. Discover the amount of spatial information needed to identify a stereogenic atom and define absolute stereochemistry. Explore the relationship between centers of chirality and overall molecular chirality.
• Absolute Configuration: Master the definitions of key stereochemical relationships, including enantiomers and diastereomers.
• Cahn-Prelog-Ingold System: Utilize the Cahn-Prelog-Ingold (C-P-I) system to assign priorities to groups around an atom and determine the R/S configuration.
• Fischer Projections: Accurately draw and interpret Fischer projections to describe the stereochemical properties of compounds with multiple stereogenic centers.
• Stereochemical Nomenclature: Learn and apply standard nomenclature:
  • D, L, R, S designations
  • Cis/Trans and E/Z nomenclature systems
• Meso Compounds: Understand and identify meso compounds – achiral compounds containing stereogenic centers.
• Atropisomers: Learn the nomenclature for atropisomers.

This course equips you with the skills to recognize and draw structural isomers (constitutional isomers) and stereoisomers, including enantiomers and diastereomers. You'll also learn to identify objects as chiral or achiral and recognize internal mirror planes.
