Why does water have a higher boiling point (100.0°C) while ethanol boils at 78.29°C? I know it has something to do with intermolecular forces.

   The intermolecular forces in water are strong. That is there is a very strong interaction. That is not the case with ethanol. Hence water needs more energy (heat) to vaporize it.
