In this video, we explore the Molecular Orbital Theory (MOT) with a clear focus on homonuclear diatomic molecules such as H₂, He₂, Li₂, Be₂, B₂, C₂, N₂, O₂, F₂, and Ne₂. Through detailed molecular orbital diagrams, you’ll learn how atomic orbitals combine to form bonding and antibonding molecular orbitals — and how this determines the bond order, magnetic properties, and stability of molecules. 📚 Topics Covered: Basics of Molecular Orbital Theory Aufbau principle and orbital energy ordering MO diagrams for 1s- and 2p-block elements Bond order calculation Explanation of paramagnetism and diamagnetism Real examples of homonuclear diatomic molecules 1.
