Chapter 7, Problem 87QRT

(a)

Interpretation Introduction

Interpretation:

The type of interactive forces which should be overcome for evaporation of ${\text{CH}}_{\text{3}}\text{OH}\left(\text{l}\right)$ 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.
