what kind of intermolec forces are in NH4Cl

i thought it was london dispersion, dipole dipole, and hydrogen bonding

and nottttt ionic.

what am i doing wrong?

  • Chem -

    The bond between NH4+ and Cl- is ionic.

    That is the bond that breaks in solution, when the compound forms two ions.

    The bonds between N and H are probably covalent, and do not break easily.

    so you mean H-N is not a hydrogen bond?

    and it is an ionic

    so the list would be

    Dispersion
    H bond
    dipole dipole?

    Hydrogen bonds, as I understand them, are weak attractive forces between hydrogen atomsin adjacent molecules of a liquid. Dipole-dipole bonds are also weak attractive forces between molecules that occasionally stick together. I have nothing else to add to my previous answer.

    DrWLS is correct. While you have H-N bonds, per se, they are not, by definition, hydrogen bonds. You do have attraction between the NH4^+ and the Cl^- ions in solution. The NH4^+ is not a dipole and it has no dipole moment although each of the N-H bonds are polar. That isn't a contradiction because to have a net dipole moment the ion/molecule must have polar bonds (which NH4^+ has) AND not be symmetrical (in space that is). The NH4^+ is symmetrical so each of the N-H bond's polarity cancels and there is no NET dipole for the ion.

    "Hydrogen bonds, as I understand them, are weak attractive forces between hydrogen atomsin adjacent molecules of a liquid." Not between hydrogen atoms, but between a hydrogen atom and an electronegative atom such as O, N or F.

    And I didn't pay attention to ALL that Bill wrote; I just read to the H atom part and stopped reading. Thanks to Dr Russ for setting it right.

    Thank you for the clarification. They are relatively weak bonds between hydrogen and another atom in a different molecule. I was confused because I had heard about the hydrogen bond between water molecules. Such bonds do not occur within NH4Cl molecules
