Chapter 7.8, Problem 7.8.4SR

Interpretation Introduction

Interpretation:

The theory or concept that explains the Para magnetism of ${\text{O}}_{\text{2}}$ should be determined.

Concept introduction:

Molecular orbital (MO) theory:

• The atomic orbitals of the atoms constituted in a molecule are combined to produce new orbitals are called Molecular Orbitals.
• Like atomic orbitals, a molecular orbital can accommodate maximum two electrons and the two electrons must have opposite spins (Pauli Exclusion Principle).
• Relative energy levels of molecules are according to the energy levels of atomic orbitals.

Paramagnetic species have one or more unpaired electrons in their molecular orbitals.

Diamagnetic species have no unpaired electrons in the molecular orbitals.
