The correct statement is the second one, which is that: ioniccompounds usually have a higher heat of vaporization than covalentcompounds. This is because ionic compounds are extremelypolar, and as a result, they have very strong intermolecularforces, so the energy required to eliminate these intermolecularforces is higher. Since the energy required to eliminatethese forces (which is necessary to vaporize) is higher, the heatof vaporization is then higher.
