WebVSEPR Theory. The VSEPR theory is used to predict the shape of the molecules from the electron pairs that surround the central atoms of the molecule. The theory was first presented by Sidgwick and Powell in 1940. The VSEPR theory is based on the assumption that the molecule will take a shape such that electronic repulsion in the valence shell ...
