Dipoles arise when?

One end of a molecule or atom has a partial negative charge and the other end has a partial positive charge.

any atom or molecule or any group placed in electric field ,induced and two pole generate..in liquid form when we take it as solvent then it exerts the force on solute molecule,if contains that...

dipole-dipole occurs between polar molecules ion-dipole occurs between mixtures of ionic compounds and polar compounds

NO. as F atom is very electronegative, it can't be polarized hence no dipole formation. F2 interaction is VanDerWaal's interaction instead.

yes! it's dipole dipole intermolecular force. The Lewis structure is a tetrahetron, but Not symmetrical, therefore it's polar, and it's dipole dipole!!
