Chapter 11, Problem 11.36P

(a)

Interpretation Introduction

Interpretation:

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