Chapter 4, Problem 18Q

Interpretation Introduction

Interpretation: The modification to the molecular orbital model, made from the experimental evidence that ${\text{B}}_{\text{2}}$ is paramagnetic, is to be stated.

Concept introduction: A permitted spatial distribution of electrons within a molecule, associated with a specific orbital energy is known as molecular orbital

To determine: The modification made to the molecular orbital model on the basis of the experimental evidence of ${\text{B}}_{\text{2}}$
