VSEPR Theory

Subject: Chemistry

Book: General Chemistry

Valence Shell Electron Pair Repulsion (VSEPR) theory explains molecular geometry by minimizing repulsion between electron pairs. Electron pairs (bonding and lone pairs) arrange themselves as far apart as possible around the central atom. Common geometries include linear (2 regions), trigonal planar (3), tetrahedral (4), trigonal bipyramidal (5), and octahedral (6). Lone pairs typically occupy more space, affecting bond angles. VSEPR provides a practical approach to predicting 3D shapes of molecules.
