Fundamentals of Chemical Bonding and Molecular Geometry

Chemical bonding is the bedrock of chemistry, determining how atoms combine and why molecules behave the way they do. Without a strong grasp of bonding theories, understanding chemical reactions and material properties is impossible. This text-based course provides a clear, conceptual foundation in chemical bonding, focusing on the essential models used by chemists. You will move beyond memorization to gain the skills needed to analyze any compound, visualize its three-dimensional structure, and predict its reactivity and physical state based solely on its electronic configuration and bond type. ### What you'll learn * Understand the differences between ionic, covalent, and metallic bonding and their associated energy landscapes. * Apply Lewis dot structures, formal charge, and resonance concepts to represent complex molecular arrangements. * Master VSEPR theory and hybridization models (sp, sp2, sp3) to determine precise molecular geometry and bond angles. * Calculate dipole moments and analyze molecular symmetry to accurately predict the overall polarity of a compound. * Explore the foundational concepts of Molecular Orbital Theory (MOT) to explain stability and magnetic behavior that Valence Bond Theory cannot cover. * Analyze the role of intermolecular forces (van der Waals, hydrogen bonding) in determining the bulk physical properties of substances. The course begins with fundamental definitions and progresses methodically through electronic theories (Lewis, VBT, MOT). We then apply these theories using written exercises focusing on predicting geometry, polarity, and structure. This course is designed for absolute beginners in chemistry, students preparing for foundational science courses, or anyone needing a robust conceptual review of inorganic bonding.
