Chapter 3, Problem 3.21QP

(a)

Interpretation Introduction

Interpretation:

Using the electronegativity values the bonds in ${\text{MgCl}}_{\text{2}}$ has to be classified as ionic, polar covalent or nonpolar covalent.

Concept Introduction:

Electronegativity is a measure of the ability of an atom to attract electrons in a chemical bond.  Elements with high electronegativity have a greater ability to attract electrons than elements with low electronegativity.

(b)

Interpretation Introduction

Interpretation:

Using the electronegativity values the bonds in ${\text{CO}}_{\text{2}}$ has to be classified as ionic, polar covalent or nonpolar covalent.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Using the electronegativity values the bonds in ${\text{H}}_{\text{2}}\text{S}$ has to be classified as ionic, polar covalent or nonpolar covalent.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

Using the electronegativity values the bonds in ${\text{NO}}_{\text{2}}$ has to be classified as ionic, polar covalent or nonpolar covalent.

Concept Introduction:

Refer to part (a).
