CHM 101 Chemical Bonding and Intermolecular Forces Objective Question

Question

When will dipole-dipole interactions likely be the dominating force between molecules?
Options
A When molecules are of comparable size and shape
Correct Answer
B When molecules are very large
C When molecules are nonpolar
D When molecules are gases
Correct Answer

Option A is the correct answer.

Detailed Explanation

If two molecules are of comparable size and shape, dipole-dipole interactions will likely be the dominating force. If one molecule is much larger than another, dispersion forces will likely determine its physical properties.

Hint

The notes provide this comparison for determining dominating forces.
