    Well, is it VDW or Dipole-Dipole?

    I saw your thread ages ago but didn't reply because I couldn't understand the title.

    Yay, Dipole-dipole

    Got that one right then. I was proper crapping myself in the exam before XD Kept crossing my answer out =/

    Wouldn't it be Van Der Waal forces? Since Dipole-dipole only occurs between hydrogen and Fluorine, Oxygen, Nitrogen or Chlorine?

    Those are hydrogen bonds, which are different to dipole-dipole forces.. right?

    I wrote dipole-dipole, then van der waals...but I think it's wrong -_-
    I only wrote van der waals because one of the other questions asked why the boiling point of the compounds increased. =/

    Hydrogen bonding = permanent dipole-dipole

    (i think that is right :ninja: )

    Dipole-Dipole there are also VDW forces in H2S but they are obviously not as strong.

    van der Waals are temporary induced dipole-dipoles. Dipole-Dipoles are permanent charge seperations. And Hydrogen bonding is a special case of dipole-dipole bonding that only appears in HF, HN and HO molecules due to the large difference in electronegativities. And yeah the strongest Intermolecular Force in H2S is Dipole-Dipole. Too bad I put vdW, I didn't really think about it too much =/.

    it's defo dipole-dipole. I put vdW, but it's not the STRONGEST IMF. So that's one mark lost :/

    Oh okay then, yeh i wrote van der waal forces as well .
    Oh well, i'm just glad that that's over now!

    I put VdW too. Which is wrong... BUT, as they didn't give us any electronegativity values, and we don't need to memorise any... we might get the mark (according to my teacher) fingers crossed eh?

    My teacher also said it was VDW :rolleyes:

    Its permanent dipole-permanent dipole (or dipole-dipole) because the S is partially negative, due to electronegativity. Thats the strongest force of attraction.

    Van Der Waal (or Instantaneous Dipole-Induced Dipole) if you're on a course like salters will also happen but its not as strong as dipole-dipole.

    It's NOT hydrogen bonding. You don't get h-bonding in any of the 'dihydrides' (is that the right term, for H2X) apart from H2O.

    Pretty stupid question if they didnt give electronegativity values or ask you to memorize anything...
