Chemistry 122 Worksheet #1 (Chpt. 12) Intermolecular Forces and Liquids and Solids 1. Describe each of the following intermolecular forces: a. Dipole-diple forces b. Ion-dipole forces c. Dispersion forces 2. Circle which has a stronger effect in an ion-dipole intermolecular force: a cation or anion? Explain your reasoning. 3. Indicate the different types of intermolecular forces that exist in each of the following substances: a. CCl 4 b. HBr 4. Circle which of the following substances should have the strongest intermolecular attractive forces: N 2, Ar, F 2 , Cl 2 . Explain your choice. 5. The dipole moment (μ) in HCl is 1.03 D, and in HCN is 2.99D. Which substance should have the higher boiling point? Why? 6. Recall that hydrogen bonds are a special type of dipole-dipole interaction between the hydrogen atom in a polar bond such as N-H, O-H, or F-H, and an electronegative O, N, or F atom. Knowing this, predict which member of each pair has the stronger intermolecular forces of attraction:
