True or False?

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

Please explain your answer.

Ummm, could you explain that a little more thoroughly?

True.The stronger dispersion forces need more broke out energy that means higher temperature rise
than that of hydrogen bonding.

False. Since water has a mole weight of 18 vs 114 for octane, the reverse is true.
