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

Question

Quizplus · Accepted Answer

The boiling point of a substance is directly related to the strength of intermolecular forces (IMFs) present in the substance. Octane is a nonpolar molecule, which means it only has dispersion forces between its molecules. On the other hand, water is a polar molecule that exhibits both hydrogen bonding and dispersion forces. Since Octane has a higher boiling point than water, we can infer that the dispersion forces in nonpolar octane molecules are stronger than the dispersion forces and hydrogen bonding in water. Therefore, the statement is true.
