Chapter 2, Problem 2.94QE

(a)

Interpretation Introduction

Interpretation:

Name of the ionic compound ${\text{NH}}_{\text{4}}\text{Br}$ has to be written.

Concept Introduction:

Naming of ionic compounds that contain monoatomic ions are given by using the name of the cation (mostly metal), which is followed by the name of anion.  The anion (mostly nonmetal) is named by adding the suffix “-ide”.

If the ionic compound contains polyatomic ions, then the name of the polyatomic ions is used directly in the name of compound without any suffix or prefix.  Overall charge of the compound has to be checked whether it is zero.

(b)

Interpretation Introduction

Interpretation:

Name of the ionic compound ${\text{BaCl}}_{\text{2}}$ has to be written.

Concept Introduction:

Naming of ionic compounds that contain monoatomic ions are given by using the name of the cation (mostly metal), which is followed by the name of anion.  The anion (mostly nonmetal) is named by adding the suffix “-ide”.  When an ionic compound is made up of only two elements, it is known as binary compounds.

In case of binary compounds, the numerical prefixes are not shown in the name because the number of ions is inferred from the empirical formula.

(c)

Interpretation Introduction

Interpretation:

Name of the ionic compound ${\text{K}}_{\text{2}}\text{O}$ has to be written.

Concept Introduction:

Refer part (b).

(d)

Interpretation Introduction

Interpretation:

Name of the ionic compound ${\text{Sr(NO}}_{\text{3}}{\text{)}}_{\text{2}}$ has to be written.
