Valence Shell Electron Pair Repulsion (VSEPR) Theory

Valence Shell Electron Pair Repulsion (VSEPR) Theory predicts the shape of a molecule based on the idea that electron pairs around an atom repel each other. These pairs, whether involved in bonds or lone pairs, position themselves as far apart as possible to minimize repulsion. This arrangement determines the overall geometry of the molecule—for example, linear, bent, or tetrahedral. VSEPR helps us understand molecular shape and bonding behavior, which is important in predicting chemical properties and reactions.
