Chapter 11, Problem 11.37P

(a)

Interpretation Introduction

Interpretation:

The order of decreasing bond energy of ${\text{B}}_2{}^{+}$, ${\text{B}}_2$ and ${\text{B}}_2{}^{-}$ on the basis of the molecular orbital diagram is to be ranked.

Concept introduction:

A molecular orbital diagram is a tool that is used to describe the chemical bonding formed between different molecules. It is used to predict the bond strength and the electronic transitions that a molecule can undergo.

(b)

Interpretation Introduction

Interpretation:

The order of decreasing bond length of ${\text{B}}_2{}^{+}$, ${\text{B}}_2$ and ${\text{B}}_2{}^{-}$ on the basis of the molecular orbital diagram is to be ranked.
