Chemistry - CHEMICAL BONDING Question with Solution | TestHub

In order to explain the characteristic geometrical shapes of polyatomic molecules like ${\mathrm{CH}}_4$, ${\mathrm{NH}}_3$ and ${\mathrm{H}}_2\mathrm{O}$ etc. pauling introduced the concept of hybridisation. According to him the atomic orbitals combine to form new set of equivalent orbitals known as hybrid orbitals. Unlike pure orbitals, the hybrid orbitals are used in bond formation. The phenomenon is known as hybridisation which can be defined as the process of intermixing of the orbitals of similar energies so as to redistribute their energies, resulting in the formation of set of new orbitals of equivalent energies and shape.
