Chapter 11, Problem 117DIA

(a)

Interpretation Introduction

To determine: If the boiling points of hydrides of group 6A are in trend with the molar masses.

(b)

Interpretation Introduction

To identify: The intermolecular force which correlates with a dipole moment.

(c)

Interpretation Introduction

To identify: The intermolecular force which correlates with polarizability.

(d)

Interpretation Introduction

To explain: The intermolecular force which is responsible for the trend of the boiling point of ${\text{H}}_2\text{S,}{\text{H}}_2\text{Se}$, and ${\text{H}}_2\text{Te}$.

(e)

Interpretation Introduction

To verify: If the answer of d is in agreement with the information of the table.

(f)

Interpretation Introduction

To identify: The intermolecular force which is responsible for the unusually high boiling point of water.

(g)

Interpretation Introduction

To draw: The diagram of phase transformation of water from liquid to a gaseous state at the molecular level by taking 6 water molecules.
