Homework Help: chemistry

What intermolecular force(s) must be overcome to do the following.

(a) sublime ice

hydrogen bonding
dipole-dipole interactions (not hydrogen bonding)
induced-dipole/induced-dipole forces
ion-dipole force

You can choose one. Can some one please explain. I know the intermolectular forces: Hydrogen bonding, dipole, and dispersion but really need help with ion-dipole and induced dipole.

I am really confused:/

Ion-dipole forces are those between an ion and a dipole; for example, between a chloride ion (Cl^-) and the dipole of a water molecule.
Induced dipole-induced dipole are also called instantaneous dipole-induced dipole. Here is a very good site that explains all of the forces including induced dipole-induced dipole.
