4.24     What is meant by hybridisation of atomic orbitals ? Describe the shapes of SP, SP^{2}, SP^{3}  hybrid orbitals.

Answers (1)

Hybridisation which can be defined as the process of intermixing of the orbitals of slightly different energies so as to redistribute their energies, resulting in the formation of a new set of orbitals of equivalent energies and shape.

The shapes of SP, SP^{2}, SP^{3}  hybrid orbitals are shown:

SP hybrid orbital: It is linear in shape and formed by intermixing of s and p orbitals.

SP^{2} hybrid orbital: It is the trigonal planar shape and is formed by the intermixing of one s-orbital and two 2p-orbitals.

SP^{3}  hybrid orbital: It is tetrahedron in shape and is formed by the intermixing of one s-orbital and three p-orbitals.
