Molecular Orbital (MO) Theory explains how atomic orbitals combine to form molecular orbitals that are delocalized over an entire molecule. Unlike valence bond theory, MO theory considers electrons in molecules to occupy orbitals that extend across the whole molecule, helping to explain properties like magnetism and bond order. When two atomic orbitals overlap constructively, they form a bonding orbital (lower in energy), and when they overlap destructively, they form an antibonding orbital (higher in energy). Electrons fill these orbitals following the Aufbau principle, Pauli exclusion principle, and Hund's rule. Bond order can be calculated as (bonding electrons - antibonding electrons)/2 — a higher bond order means a stronger, more stable bond. MO theory is especially useful for diatomic molecules like O₂, explaining its paramagnetic behavior due to unpaired electrons in antibonding π* orbitals. #ChemTok #MolecularOrbitalTheory #BondOrder #QuantumChemistry #StudyWithMe #ScienceExplained #FYP #PreMed #ChemLife
