Identify the likely kinds of intermolecular forces in each of the following substances.

• PART A

Al2O3, F2, H2O, Br2, ICl, and NaCl.

THE ANSWER CHOICES FOR EACH ONE ARE (NOTE: THEY'RE THE SAME FOR EACH ONE):

***CHECK ALL THAT APPLY (FOR EACH ONE)***

-dispersion

-ionic

-dipole-dipole

-H-bonding

• PART B

Using your knowledge of the relative strengths of the various forces, rank the substances in order of decreasing of their normal boiling points. RANK COMPOUNDS IN ORDER OF DECREASING OF THEIR NORMAL BOILING POINTS. (***NOTE: RANK FROM HIGHEST BP TO LOWEST BP***)

Al2O3, F2, H2O, Br2, ICl, and NaCl.
