Octane, C₈H₁₈, boils at 125°C, whereas water boils at 100°C. This information suggests that the dispersion forces in nonpolar octane molecules are stronger than the dispersion forces and hydrogen bonding in water.

Question

Quizplus · Accepted Answer

Boiling point is directly related to the strength of intermolecular forces. Since octane has a higher boiling point than water, it indicates that the forces between octane molecules (dispersion forces) are stronger than the forces between water molecules (dispersion forces and hydrogen bonding).
