WebHydrogen bonding is a type of intermolecular force that occurs between a hydrogen atom bonded to an electronegative atom (such as oxygen, nitrogen, or fluorine) and another electronegative atom. In the case of ethanol, the hydrogen atom in the hydroxyl group can form hydrogen bonds with other molecules of ethanol or with water molecules. WebThe vast majority of energy needed to boil water comes right before it's at the boiling point. It takes way less energy to heat water to 90ºC than to 100ºC, so the relative amounts of energy required to boil ethanol vs. water are actually as large as stated in the video. It's not really intuitive, but it's one of the odd things about water ...
