Chapter 22, Problem 38E

Interpretation Introduction

(a)

Interpretation:

The reason for the oxygen-to-oxygen bond lengths in ${\text{O}}_{\text{2}},{\text{ O}}_{\text{3}}{\text{and H}}_{\text{2}}{\text{O}}_{\text{2}}$ to be $\text{121},\text{ 128},\text{ and 148 pm}$ respectively needs to be explained.

Concept introduction:

Bond length is inversely proportional to bond order means if bond order is more bond length will be less. Here, bond order is defined as number of electrons involved in the bonding.

Interpretation Introduction

(b)

Interpretation:

The reason for bond length for ${\text{O}}_{\text{2}}{}^{+}\left(\text{112 pm}\right)$ to be shorter than ${\text{O}}_{\text{2}}\left(\text{121 pm}\right)$ needs to be explained.

Concept introduction:

Bond length is inversely proportional to bond order means if bond order is more bond length will be less.
