Chapter 7, Problem 60QRT

(a)

Interpretation Introduction

Interpretation:

The type of interactive forces which should be overcome for sublimation of ${\text{C}}_{\text{10}}{\text{H}}_{\text{18}}$ has to be given.

Concept Introduction:

The set of repulsive and attractive force between molecules that result from the polarity between neighboring molecules is represented as intermolecular force. There are four types of intermolecular forces:

• Hydrogen bonding.
• London dispersion force.
• Ion – dipole force.
• Dipole – Dipole force.
