Valence shell electron pair repulsion (VSEPR) theory

Valence shell electron pair repulsion (VSEPR) theory is a model in chemistry used to predict the shape of individual molecules based upon the extent of electron-pair electrostatic repulsion. It is also named Gillespie-Nyholm theory after its two main developers. The premise of VSEPR is that the valence electron pairs surrounding an atom mutually repel each…
