Hydrogen Bonding

How does hydrogen bonding affect the melting points of compounds?

Hydrogen bonding is a very strong intermolecular force, so the forces between the molecules are much stronger compared to other forces like dipole-dipole or dispersion forces. Melting point is increasing the energy of the atoms so that they go from solid to liquid, and if the attractive forces are stronger, it will take more energy to melt the solid.

molecules with hydrogen bonding will have much higher boiling points because they are much more difficult to break apart

When a compound melts, it goes from solid to liquid, increasing the distance between molecules. Hydrogen bonding is a strong intermolecular force, so with hydrogen bonding, increasing the distance between molecules within a compound is harder, requiring more energy, thereby resulting in a higher melting point.
