*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. Use your knowledge of intermolecular forces to provide an explanation for why the boiling point of 2-hexanol is higher than the boiling point of 2,3-dimethyl-2-butanol. Be sure to...
