Is Hydrogen Bonding a type of Dipole-Dipole Interaction?
So is hydrogen bonding just a specific type of dipole-dipole interaction? If so, if we say two molecules have hydrogen bonding, then is it implied that there are dipole-dipole interactions between them also so that we don't have to state that explicitly?

yes, hydrogen bonding is just a specific category under the larger umbrella of dipole-dipole interactions. If you say that hydrogen bonding exists between two molecules, then it generally goes without saying that there is an intermolecular dipole-dipole force between the molecules

Yes, so if someone says there is hydrogen bonding present, you can assume that dipole-dipole is also present. The opposite is not true though. If it is said that dipole-dipole interactions are taking place, you cannot say that hydrogen bonding is also present without more information!

But for things like exam 3, I think it would be best to state that both hydrogen bonding and dipole-dipole interactions are present

If the final asks for the intermolecular forces in a molecule, can we always write that London forces are present or are there cases where they are not?

I believe Lavelle said that London Dispersion Forces are always present in between molecules that are close to each regardless of whether they are polar or nonpolar.
