Chapter 17, Problem 121AE

(a)

Interpretation Introduction

Interpretation:The more soluble substance in water out of ${\text{CH}}_{\text{3}}{\text{NH}}_{\text{2}}$ or ${\text{NH}}_{\text{3}}$ needs to be determined.

Concept Introduction:

The intermolecular forces exist between different molecules and are mainly 4 types:

• London dispersion force
• Hydrogen bond
• Dipole-dipole bond
• Ion-dipole bond

The presence of different types of intermolecular forces affects the boiling point, melting point, solubility, etc.

(b)

Interpretation Introduction

Interpretation: The more soluble substance in water out of ${\text{CH}}_{\text{3}}\text{CN}$ or ${\text{CH}}_{\text{3}}{\text{OCH}}_{\text{3}}$ needs to be determined.
