Can somoneone explain how Hydrogen Bonding raises melting point?

I realize that strong intermolecular bonds make it more difficult for molecules to escape and thus the boiling point is raised; but why does it increase melting point as well. Is it because the lattice is easier formed and thus, freezes at a higher temperature, or thus freely melts at a higher temperature?

strong intermolecular forces in general promote the less disordered state.

Think about it like this: What does hydrogen bonding do? It stabilizes: it stabilizes DNA, water, proteins, etc. Whether you are looking at a solution or a compound, if it is stable, then it will require more energy to make it unstable.

If you are trying to cause a phase change of a compound, the more stable it is, the more energy required to break bonds/de-stabilize it. In the cases of boiliing point/melting point, the more stable the compound, the higher the values.

I hope that makes sense.

^ Thank you that makes perfect sense!
