Chapter 2, Problem 2.64QP

Interpretation Introduction

Interpretation: The mythical element $\text{X}$ is considered which forms only two oxoanions ${\text{XO}}_2{}^{2-}$ and ${\text{XO}}_3{}^{2-}$. The oxoanion, among the given oxoanions, that requires a prefix such as $hypo-$ or $per-$ is to be determined.

Concept introduction: The compound which contains a chemical element and more than one oxygen atom is known as oxoanions. It represents by the general formula ${\text{A}}_{\text{X}}{\text{O}}_{\text{Y}}{}^{\text{Z}-}$. The suffix used in the naming depends upon the number of oxygen atoms that are given in the formula of the oxoanions. It is either $-ite$ and $-ate$.

To determine: If any of the oxoanion, among the given oxoanions, requires a prefix such as $hypo-$ or $per-$.
