1. Tell which of the following compounds are likely to have a dipole moment, and show the
net dipole for each. If there is no dipole moment, write no dipole moment.
2. Identify the kinds of intermolecular forces in each of the following substances (hydrogen

c. HF d.
e. CH3OH f.
g XXXXXXXXXXh.
i XXXXXXXXXXj.

oiling point?
4. Consider the two substances BrCl and IBr. One is a solid at room temperature and one is a
gas. Which substance is a gas? Which is a solid? Explain.
5. List the substances H2, CO, HF and Ne in order of increasing boiling point.
6. List the substances Ar, Cl2, CH4, and CH3CO2H in order of increasing strength of
intermolecular forces.
7. Which of the following substances would you expect to have the highest boiling point:
CH3CH3, CH3OH, or CH3CH2OH?
