Jul 3, 2023 · Learn the basics of Valence Shell Electron Pair Repulsion Theory (VSEPR) with examples and calculations. In this doc you can find the meaning of VSEPR Theory: Definition, Postulates & Limitations | Chemistry Class 11 - NEET PDF Download defined & explained in the simplest way possible. The VSEPR theory is based on the assumption that the molecule will take shape such that electronic repulsion in the valence shell of that atom is minimised. This results in greater repulsion theoretical basis of the VSEPR theory regarding between lone pairs of electrons as compared the effects of electron pair repulsions on to the lone pair - bond pair and bond pair - molecular shapes is not clear and continues bond pair repulsions.
