Chapter 3, Problem 34P

(A)

Interpretation Introduction

Interpretation:

The compound with higher boiling point from MgBr₂ or PBr needs to be determined.

Concept Introduction:

To determine the boiling point of any compound, electronegativity difference of the elements of the compound needs to be calculated. As the electronegativity difference increases, boiling point also increases because more electronegative compound means high bond energy and that higher energy needs too much temperature to boil. This concept can be used to determine the boiling point of the given compounds.

(B)

Interpretation Introduction

Interpretation:

The compound with higher boiling point from OsO₄ or SrO needs to be determined.

Concept Introduction:

To determine the boiling point of any compound, electronegativity difference of the elements of the compound needs to be calculated. As the electronegativity difference increases, boiling point also increases because more electronegative compound means high bond energy and that higher energy needs too much temperature to boil. This concept can be used to determine the boiling point of the given compounds.

(C)

Interpretation Introduction

Interpretation:

The compound with higher boiling point from Cl₂O or Al₂O₃ needs to be determined.
