Do both HF and NH3 have london-dispersion forces, dipole-dipole and hydrogen bonding?

All of these intermolecular forces operate in hydrogen fluoride, and ammonia.

Explanation:

While all of these forces operate, hydrogen bonding is the most significant intermolecular force that operates. Consider the boiling points of #NH_3#, and #HF#; #-33# #""^@C#, and #19.5# #""^@C#, and boiling point is probably the best indicator of intermolecular force.

Both pure ammonia and pure hydrogen fluoride have their own particular acid/base chemisty that may be compared with the #OH^-, H_3O^+# couple that operates in water.
