Question

1. Describe how intermolecular forces might be responsible for the observed order of melting points for Naphthalene, Iodine, Sucrose, and NaCl. 2. Describe how intermolecular forces might be responsible for the observed order of evaporation rates for ethanol, methanol, and acetone. 3. How do you think water and glycerol’s rate of evaporation would compare to the rates for ethanol, methanol, and acetone? Faster or slower? Explain your answer using intermolecular forces. 4. In which solvent (hexane/water) did iodine and NaCl dissolve? Describe how intermolecular forces might be responsible for the observed solubility or insolubility of iodine and NaCl in hexane and water. Be specific in your response; include which intermolecular forces are involved.
