What is VSEPR theory?

VSEPR is the acronym for Valence Shell Electron Pair Repulsion theory. VESPR is a model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule's valence electrons around a central atom.

According to Google : Valence shell electron pair repulsion ( VSEPR ) theory is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. It is also named the GillespieNyholm theory after its two main developers.
