Name the kind(s) of attractive forces that must be over come in order to do the following:

dissolve CsI in liquid HF

dipole-dipole
dispersion
ion-ion
ion-diople
metallic bonds

I believe the first two forces are present and then one of the ion forces?

Solution Preview

To dissolve CsI, you must break the CsI into separate ions. If you look at the electronegativity difference, you find:

Cs - 0.79
I - 2.66

Difference - 1.87

Anything above 2 is ionic. 1.87 is very close, so CsI is also ...

Solution Summary

This solution explains what attractive forces must be overcome for CsI to dissolve in HF.
