What is Valence Shell Electron Pair Repulsion?
The VSEPR theory predicts molecular geometry by minimizing repulsion between electron pairs (bonding and lone pairs) around a central atom. Lone pairs repel more strongly than bonding pairs, causing deviations from ideal bond angles. Explains why water is bent and ammonia is pyramidal.

The VSEPR theory predicts molecular geometry by minimizing repulsion between electron pairs (bonding and lone pairs) around a central atom. Lone pairs repel more strongly than bonding pairs, causing deviations from ideal bond angles. Explains why water is bent and ammonia is pyramidal.
VSEPR is used to predict and explain the shapes of molecules and polyatomic ions. It guides chemists in understanding polarity, reactivity, and physical properties of compounds. VSEPR predictions are the starting point for understanding molecular geometry before more detailed calculations.
VSEPR is a theoretical model with no direct safety implications. Molecular geometry predicted by VSEPR affects the polarity and biological activity of molecules.
