Question: What is the strongest interparticle force in each substance? (a) H3PO4 (b) SO2 (c) MgCl2
My Approach:
(a) hydrogen bonding
(b) dipole-dipole
(c) dispersion forces
these kinda questions throw me off. appreciate all the help i can get!

a) H3PO4 - anhydrous - hydrogen bonding - look at all the free O's and then the H's form the acid moiety.
b) SO2 - dipole - dipole ONLY! Nothing else for this in the gas phase. If you bring it into the liquid phase you may get weak dispersion forces - but I doubt that is the question - or answer to the problem.
c) MgCl2 - is a weak lewis acid - so is means is can act as an electron acceptor. So I would predict that in the solid state it would be dominated by dipole-dipole interactions (Clorine has a lot of electrons to give, Mg want an electron).

a) yes this molecule indeed has hydrogen bonding.
b)dipole-dipole is correct here. S02 is a bent molecule so it is polar. That means there can be dipole-dipole bonds.
c)actually this is a typical ionic substance so it has a network of ionic bonds. To talk about intermolecular forces doesn't really make sense here because there are no "molecules". The bonds holding the substance together are ionic bonds.

Hydrogen Bond is strongest

Dispersion forces are not strong anywhere in here, as none of them are inert gases.
MgCl2= ion ion interaction
and rest i dont know!

I think it depends

You're right on (a) and (b). (c) is ionic,
