Is Hydrogen bonding strong or weak bonding?

[rak173]

Some sources say it is extremely strong (which gives properties to H2O) and some sources say it is a weak bonding (like in feralis). I know it is a weak bond compared to the Ionic bondings but a stronger bond than other bondings like london dispersion, dipole-dipole etc. So if a question asks if it's a weak or strong bond, what should I go with?

hydrogen bonding is an intermolecular force, not a strong or weak bond. An intermolecular force is an attractive force that keeps neighboring molecules together. Although hydrogen bonding is the strongest intermoelcular force, it is considered weaker than any bond (ionic, covalent).

It's all relative, so such a question wouldn't make sense by itself. H bonding is usually considered the strongest intermolecular force (between 2 different molecules) but is still way weaker than the weakest intermolecular force (inside a single molecule), say like a covalent bond.

When I think about strong H-bonding, I think about about it in terms of intermolecular forces. H-bonding >dipole-dipole > london-dispersion
it'll be helpful if you post the question.

its a pretty strong inter-molecular bonding. it just depends with what you are comparing it to.

Intra-molecular bonding > inter-molecular bonding.

see attached image. as you go down, forces becomes weaker.
