Chapter 11, Problem 11.50QE

(a)

Interpretation Introduction

Interpretation:

The type of intermolecular force present in methane has to be identified.

Concept Introduction:

Intermolecular forces:  Intermolecular forces are electrostatic in nature and include van der Waals forces and hydrogen bonds.  Molecules in liquids are held to other molecules by intermolecular interactions, which are weaker than the intramolecular interactions that hold the atoms together within molecules and polyatomic ions.  The three major types of intermolecular interactions are,

• Dipole-dipole interactions
• London dispersion forces
• Hydrogen bonds
