Water, which it has hydrogen bonds, has a higher melting point because of the interactions between the molecules. The Oxygen's of each molecule has a slight negative charge and this has an intramolecular attraction with the Hydrogen of another water molecule. So, this attraction means it takes more energy (for temperature, it would be heat) to separate this interaction between molecules, and thus, the melting/boiling point of water is higher than you would expect for a small molecule.
