The boiling point of methanol is much higher than that of ethane.This is primarily due to

Question

Quizplus · Accepted Answer

The hydrogen bonding in methanol is the primary reason for its higher boiling point. Methanol has a hydroxyl group that allows for hydrogen bonding to occur between molecules, while ethane does not have any such functional group. Intermolecular hydrogen bonds require more energy to break than the weaker van der Waals forces between ethane molecules, resulting in a higher boiling point for methanol.
