Chapter 17, Problem 33E

(a)

Interpretation Introduction

Interpretation: The molecule between ${\text{NH}}_{\text{3}}$ and ${\text{PH}}_{\text{3}}$ , which is more soluble in water needs to be determined.

Concept Introduction : A substance is soluble in water by forming hydrogen bonds with the water molecules.

(b)

Interpretation Introduction

Interpretation: The molecule between ${\text{CH}}_{\text{3}}\text{CN}$ and ${\text{CH}}_3{\text{CH}}_{\text{3}}$ , which is more soluble in water needs to be determined.

Concept Introduction : A substance is soluble in water by forming hydrogen bonds with the water molecules. Polar substance is dissolved more in polar solvent.

(c)

Interpretation Introduction

Interpretation: The molecule between ${\text{CH}}_{\text{3}}\text{COOH}$ and ${\text{CH}}_{\text{3}}{\text{COOCH}}_3$ , which is more soluble in water needs to be determined.

Concept Introduction : A substance is soluble in water by forming hydrogen bonds with the water molecules.
