VSEPR Theory: Electron pairs arrange to minimize repulsion Order: LP-LP > LP-BP > BP-BP Bond Angles (ideal): Linear: 180° Trigonal Planar: 120° Tetrahedral: 109.5° Trigonal Bipyramidal: 90°, 120°, 180° Octahedral: 90°, 180° Hybridization: 2 domains → sp 3 domains → sp² 4 domains → sp³ 5 domains → sp³d 6 domains → sp³d² Molecular Polarity: Polar: dipoles don't cancel (asymmetric) Non-polar: dipoles cancel (symmetric) LP affects shape and polarity
Real-World Connection: VSEPR theory explains why water is bent (104.5°) and polar, making it a universal solvent. Drug design relies on molecular geometry to predict how molecules bind to receptors, and materials science uses VSEPR to engineer catalysts with specific active site geometries.
