Chapter 4, Problem 7E

a)

Interpretation Introduction

Interpretation: Boiling point trends that are highlighted below should be determined.

  

Concept introduction: Boiling is used to define when a substance gets converted from its liquid to the vapor phase at the boiling point. The temperature where the vapor pressure of the liquid becomes equal to surrounding or atmospheric pressure is called the boiling point. It depends on the strength of intermolecular forces. Stronger the intermolecular forces, higher will be the boiling point of the molecule and vice-versa. The magnitude of the boiling point increases with an increase in molecular mass and surface area.

b)

Interpretation Introduction

Interpretation: Reason for alkane line to be farthest to right in below graph should be determined.
