Chapter 15, Problem 15.1TC

Interpretation Introduction

(a)

Interpretation:

The difference between gases and liquids at the particulate level is to be stated that is responsible for differences in their macroscopic properties.

Concept introduction:

There are three types of interactions through which the molecules are stabilized. They are hydrogen-bonding interactions, the dipole-dipole interactions and the induced dipole interactions. These interactions influence the properties of the compounds like boiling point, melting point and so on.

Interpretation Introduction

(b)

Interpretation:

Among A and B, the one having higher surface tension, molar heat of vaporization, vapor pressure, boiling point, and viscosity is to be stated.

Interpretation Introduction

(c)

Interpretation:

Among X and Y, the one having higher vapor pressure is to be stated. The reason for the answer is to be stated.
