Study of Bent Rule and Energetics of Hybridization

Abstract

Hybridisation is the concept of mixing atomic orbitals into new hybrid orbitals with different energies, shapes, etc. than the component atomic orbitals. When a set of hybrid orbital is constructed by a linear combination of atomic orbitals, the energy of the resulting hybrids is a weighted average of the energies of the participating atomic orbitals. This energy of hybridization is of the order of magnitude of bond energies and can thus be important in determining the structure of molecules.
Bent rule encompasses the relationships between bond polarity (ligand electronegativity) and central -atom geometry through their mutual connection to central-atom hybridization.
