Chapter 6, Problem 2CGP

(a)

Interpretation Introduction

Interpretation:

Polarity of all compound should be identified.

Concept introduction:

Separation of charge takes place in a molecule containing opposite ions which results in appearance of charge between the two ions. The charge separation takes place due to the electronegative difference between the ions of opposite charges. One ion gets positive whereas other gets negative charge.

(b)

Interpretation Introduction

Interpretation:

Intermolecular forces of all compounds should be identified.

Concept introduction:

Intermolecular forces are the forces of attraction between the molecule of a compound present however the interaction is quite high if the compound having some sort of polarity between the molecules which results in the stronger interaction.

(c)

Interpretation Introduction

Interpretation:

Molar mass of all compounds should be identified.

Concept introduction:

Molar mass of compound can be determined as follows:

(d)

Interpretation Introduction

Interpretation:

Boiling point of all compounds should be identified.

Concept introduction:

Due to the increase in bulkiness of the compound the molar mass increases and hence the iodomethane having the highest boiling point of all.

(e)

Interpretation Introduction

Interpretation:

Boiling point vs molar mass graph should be identified.

Concept introduction:

With increase in molar mass of compound the boiling point increases as the bulkiness of the molecule increases which results in raising the temperature of a molecule and thus the boiling point increases.

(f)

Interpretation Introduction

Interpretation:

Relation of boiling point with molar mass should be identified.

Concept introduction:

With increase in molar mass of compound the boiling point increases as the bulkiness of the molecule increases which results in raising the temperature of a molecule and thus the boiling point increases.
