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

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.
