Chapter 14, Problem 80AP

Interpretation Introduction

(a)

Interpretation:

The structures of the four given molecules must be drawn indicating whether those are polar or non polar.

Concept Introduction:

Lewis structure is the representation of molecules showing the electron dots present in each atom.

A polar molecule has non zero bond moments whereas a non polar molecule has zero bond moments.

Interpretation Introduction

(b)

Interpretation:

Which two molecules are liquid and which two are gases as room temperature must be predicted along with proper explanation.

Concept Introduction:

For liquids intermolecular forces are stronger as compared to gases.

Interpretation Introduction

(c)

Interpretation:

The given compounds must be ranked from lowest to highest boiling point with proper justification.

Concept Introduction:

Molecules having stronger intermolecular forces show higher boiling points.
