Assuming that molar masses are comparable, which of the following compounds would you expect to have the highest boiling point?

Question

Quizplus · Accepted Answer

Alcohols have highest boiling point because they can hydrogen bond with other alcohol molecules. Aldehydes and ketones can also hydrogen bond but to a lesser extent. Alkenes have a lower boiling point than alkanes because they have less surface area for Van der Waals forces to operate. Alkanes can have similar boiling points to alcohols but they cannot hydrogen bond, so alcohols have higher boiling points.
