Limitations of Valence Bond Theory
They are: It fails to explain the tetravalency of carbon. This theory does not discuss the electrons' energies. The assumptions are about the electrons being localized to specific locations.
Many approaches have been put forth to explain the nature of bonding in coordination compounds. One of them is the Valence Bond (VB) Theory. The Valence Bond Theory was developed in order to explain chemical bonding using the method of quantum mechanics. This theory primarily focuses on the formation of individual bonds from the atomic orbitals of the participating atoms during the formation of a molecule.
What is Valance Bond (VB) Theory?
According to the valence bond theory,
Electrons in a molecule occupy atomic orbitals rather than molecular orbitals. The atomic orbitals overlap on the bond formation and the larger the overlap the stronger the bond.
The metal bonding is essentially covalent in origin and metallic structure involves resonance of electron-pair bonds between each atom and its neighbors.
