Chapter 2, Problem 2.100P

(a)

Interpretation Introduction

Interpretation:

The correct name for ${\text{CaCl}}_2$ 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 the compound ${\text{Cu}}_2\text{O}$ 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.

(c)

Interpretation Introduction

Interpretation:

The correct name for the compound ${\text{SnF}}_4$ 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.

(d)

Interpretation Introduction

Interpretation:

The name for the compound $\text{HCl}$ is to be determined.

Concept introduction:

Acids are substances that release ${\text{H}}^{+}$ ions when mixed with water. Acids are classified as binary and oxoacids. Binary acid solutions are formed by the dissolution of gaseous compounds in water. In binary acids, hydrogen is combined with a second non-metallic element. Examples are $\text{HCl}$, $\text{HBr}$, $\text{HI}$ etc.

The general formula for naming binary acids is,

$\text{prefix hydro}+\text{non-metal root}+\text{suffix}-ic+\text{acid}$ (1)
