Interpretation Introduction

Interpretation: The reason as to why hybrid orbitals are used to explain bonding in ${\text{N}}_{\text{2}}$

and ${\text{O}}_{\text{2}}$, but not used for ${\text{H}}_{\text{2}}$

or ${\text{Br}}_{\text{2}}$

is to be explained.

Concept introduction: Hybrid orbital theory is based upon the formation of hybrid orbitals by mixing of atomic orbitals.

To explain bonding by hybrid orbitals, the number of electrons around the central atom are determined by drawing the Lewis structure of the molecule.

Excitation of electrons to higher orbitals occurs to get the highest number of unpaired electrons.

The required number of hybrid orbitals are combined to obtain the hybridization of the central atom.
