Back to top 4. The Valence Shell Electron Pair Repulsion (VSEPR) theory is a simple and useful way to predict and rationalize the shapes of molecules. pw. Explain the Valence Shell Electron Pair Repulsion Theory is the VSEPR theory and is also termed as Gillespie-Nyholm Theory which helps in predicting the geometry or shape of the molecule of a compound. Explain the postulates of Vsepr theory and to predict the geometrical shapes of molecules based on it. Here shared pairs and lone pair of electrons play a vital role. A lone pair of electrons takes up more space around the central atom than a bond-pair, since the lone pair is attracted to one nucleus whilst the bond pair is shared by two nuclei. Three of these electrons are mutually shared with the electrons of three hydrogen atoms to form three N- H bonds as shown. What is VSEPR theory?
