VSEPR (Valence Shell Electron Pair Repulsion) theory explains that electron pairs around a central atom repel each other and arrange themselves to maximize distance, determining molecular geometry: linear (180°) for 2 electron pairs like Cl2, trigonal planar (120°) for 3 pairs like BF3, tetrahedral (109.5°) for 4 pairs like CH4, trigonal pyramidal for 3 bonding pairs + 1 lone pair like PCl3, and octahedral for 6 pairs like PCl5.
