Why do hydrogen bonds yield melting points?

All bonds are associated melting points; it just refers to the amount of energy required to break the bond. All bonds have an energy associated with them, so the stronger the bond, the higher the melting point.

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.

All a melting point is, is vibrating the atoms enough so they can roll past each other, if they're bonded to each other this inhibits their ability to roll past each other.
