Chapter 2, Problem 2.94P

(a)

Interpretation Introduction

Interpretation:

The correct name for $\text{CuI}$ is to be determined.

Concept introduction:

The general rules for naming ionic compounds are:

1) The cation or metal is named first followed by the name of the anion or nonmetal for naming all ionic compounds.

2) For binary ionic compounds, the cation name is the same as that of the metal whereas the anion name has the suffix $-ide$ added to it.

(b)

Interpretation Introduction

Interpretation:

The correct name for $\text{Fe}{\left({\text{HSO}}_4\right)}_3$ is to be determined.

Concept introduction:

Polyatomic ions are those in which atoms of more than one elements are present. Generally, the majority of the polyatomic ions are oxoanions in which a non-metal is bonded to one or more oxygen atoms.

The general rules for naming a family of two oxoanions are:

1) The ion with more oxygen atoms takes the non-metal root and the suffix $\text{-}ate$.

2) The ion with fewer oxygen atoms takes the non-metal root and the suffix $\text{-}ite$.

The correct name for ${\text{MgCr}}_2{\text{O}}_7$ is to be determined.
