Chapter 22, Problem 22.41SP

Interpretation Introduction

(a)

Interpretation:

The more covalent compound from ${\text{PCl}}_{\text{3}}{\text{ or AlF}}_3$ needs to be determined.

Concept introduction:

The covalent compounds are formed by non-metals and metals form ionic compounds. On moving from left to right in a periodic table, the non-metallic character increases and it decreases on moving from top to bottom in a group.

Interpretation Introduction

(b)

Interpretation:

The more covalent compound from $\text{CaO or NO}$ needs to be determined.

Concept introduction:

The covalent compounds are formed by non-metals and metals form ionic compounds. On moving from left to right in a periodic table, the non-metallic character increases and it decreases on moving from top to bottom in a group.

Interpretation Introduction

(c)

Interpretation:

The more covalent compound from ${\text{NH}}_{\text{3}}\text{ or KH}$ needs to be determined.

Concept introduction:

The covalent compounds are formed by non-metals and metals form ionic compounds. On moving from left to right in a periodic table, the non-metallic character increases and it decreases on moving from top to bottom in a group.

Interpretation Introduction

(d)

Interpretation:

The more covalent compound from ${\text{SnO}}_2{\text{ or SiO}}_2$ needs to be determined.

Concept introduction:

The covalent compounds are formed by non-metals and metals form ionic compounds. On moving from left to right in a periodic table, the non-metallic character increases and it decreases on moving from top to bottom in a group.
