2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...

*Explanations should be brief. Draw a box around each final answer, if applicable.* 1. Consider intermolecular forces and kinetic energies with respect to a solid and a liquid. Explain why molecules in a liquid are free to move past each other, while molecules in a solid are held in fixed positions. 2.

9. (4 pts.) When refluxing, a mixture of toluene and water is refluxing and condensing in the Hickman still head. A specific mixture of toluene and water will actually boil at a LOWER TEMPERATURE then either pure toluene or pure water. This is the azeotrope mixture, toluene and water can from an azeotrope. The practical consequence of this is that the toluene solvent will always have at least some water in it when it boils, which is how we are...
