Why do atoms combine? Why are only certain combinations possible? Why do molecules possess definite shapes? To answer such questions different theories and concepts have been put forward from time to time. In this fourth unit of class 11 chemistry, we can answer the above questions by learning Kössel-Lewis approach, Valence Shell Electron Pair Repulsion (VSEPR) Theory, Valence Bond (VB) Theory and Molecular Orbital (MO) Theory.
