    it makes me confused tell me am i right?

    tell me is the force between the permanent polar molecules like HCL Van der waal force?

      van der whall are the force between tempary polarity , so i gather, where electrons are alwasy moving in orbitals, adn alwasy ocuring that one atom migh have more, thus a negative charge. but move so quickly.

      perment dipole-dipole forces are.. betwen the permenant poles. these permanent poles are due to electronegativity, whis is due to the size of the atom (i think).

      i think you knew that.... so heresthe answer to what you asked: but some chemists refer to the two as van der whall forces. this is accepted, so your both right and wrong.

      you may also hear them refered to as london forces,

      i read about that i found some chemists says that Van der waal forces are two types:
      Despersion forces which sometimes called induce dipole-induce dipole and dipole induce dipole.

      Dipole -Diple forces which occurs between permanent polar molecules.

      they are other intermolecular forcec like hydrogyn forces

      My confusion was in these dividing.........

      hydrogen bonding only occurs, in flourine, hydrogen and nitrogen (oxygen too).
      i don't think these can be classed as van der whall for this reason,
      but they are dipole dipole, so far as i know
      i think as long as you understand em, and can identify em as a name accepted by chemists, it should be ok!

      yes i know that hydrogyn bonding is not Van der waal's force
