IMF on Liquids and Solids Name: Answer Key 1. Ion-dipole force always require __. a. an ion and a water molecule b. a cation and a water molecule c. an anion and a polar molecule ✔ d. an ion and a polar molecule e. a polar and a nonpolar molecule 2. Which substance in each of the following pairs would you expect to have a higher boiling point? a. O2 and Cl2 Cl2 b. SO2 and CO2 SO2 c. HF and HI HF d. F2 and LiF LiF 3. The following compound have the same molecular forces (C4H10). Which one would you expect to have a higher boiling point? Explain your answer. A B Molecule A has higher boling point. Van der Waals forces are dependent on surface area. Both molecules have dispersion forces and have the same molecular mass but molecule A has larger surface area thus stronger IMF. 4. HCl (MW=36.5) has a dipole moment of 1.03 D and a boiling point of 190K. HBr (MW=80.9) has a dipole ...
