Chapter 8, Problem 8.49PAE

Interpretation Introduction

Interpretation:

For each of the given pair of compounds, member having the higher boiling point should be identified.

Concept introduction:

• Intermolecular forces are much weaker than the chemical bonds but they are largely responsible for the structure of any solid or condensed phase.
• Dispersive forces are intermolecular attractive forces arisen from an instantaneous dipole-induced dipole attraction between molecules.
• In the molecules containing hydrogen attached to a highly electronegative atom, the intermolecular electrostatic attraction forces are very strong between the hydrogen of one molecule and the electronegative atom of another, this is called hydrogen bonding.
• Vapor pressure decreases and boiling point increases with increase in strength of intermolecular forces.

Interpretation Introduction

To determine:

Member having the higher boiling point for each of the given pair of compounds.
