Compared to compounds that possess only dipole-dipole intermolecular forces, compounds that possess hydrogen bonding generally:
have higher melting points
have lower boiling points
have the same melting points
have lower melting points

I think the correct answer from the choices listed above is the first option. Compared to compounds that possess only dipole-dipole intermolecular forces, compounds that possess hydrogen bonding generally have higher melting points. This is because hydrogen bonding is a stronger force than dipole-dipole.
