Chapter 7, Problem 7.120QP

Interpretation Introduction

Interpretation: The ground-state electron configuration of ${\text{B}}_{\text{2}}$ should be written. To find whether ${\text{B}}_{\text{2}}$ is a paramagnetic or diamagnetic species

Concept Introduction:

• In molecular orbital theory, when the bonding takes place the atomic orbitals that take part combine to get a new orbital that has the properties of the whole molecule.
• The orbital with lower energy gets the electron first and each orbital only contain a maximum of two electrons. It obeys Hund's Rule.
• There are two types of molecular orbitals- bonding molecular orbitals and antibonding molecular orbitals.
• If molecular species contains at least one unpaired electron, then they are paramagnetic. They tend to get attracted towards the magnetic field. Whereas in diamagnetic species there is no unpaired electrons and are slightly repels the magnetic field.
