Intermolecular forces: Between alkanes, the presence of van der Waals forces. Between alcohols, the presence of hydrogen bonding Hydrogen bonding are much stronger than VdW forces and therefore it takes more energy to separate alcohol molecules than it does to separate alkane molecules. Therefore, boiling point of alcohols is higher than alkanes.
