Question

Are dipole dipole forces weak?

Answer 1

See below:

Explanation:

It depends in what context you put it in.

Dipole-Dipole interaction is an intermolecular force that acts between molecules, so it is inherently much weaker than the intramolecular bonds such as ionic, covalent or metallic- so in this context it is weak.

However when comparing to other intermolecular interactions it is more noticable. In a comparison between other intermolecular interaction it is often put between H-bonding and LDF.

London dispersion force < Dipole-Dipole< Hydrogen bonding.

So in that sense it is a moderate intermolecular force.

Summary:
Yes, it is a weak interaction but it is not the weakest interaction.
