CHM 101 Chemical Bonding and Intermolecular Forces Objective Question
Take CBT

Question

Why do substances with stronger intermolecular forces generally have higher boiling points?
Options
A More energy is required to overcome the stronger attractions between molecules to enter the gas phase
Correct Answer
B They have higher molecular masses
C They have weaker covalent bonds
D They are always ionic
Correct Answer

Option A is the correct answer.

Detailed Explanation

Substances with stronger intermolecular forces have higher boiling points because more energy is required to overcome these attractions and separate molecules from the liquid phase into the gas phase. The strength of intermolecular forces directly correlates with the energy needed for vaporization.

Hint

Boiling requires overcoming intermolecular attractions.
