Problem 1: What is the chemical formula and molar mass for water? Isopropyl alcohol's formula is C3H8OH. Draw the Lewis structures for both and make molecular models for each. Based on the molar mass, which compound would you expect to evaporate first? Based on what you know about intermolecular forces, how do you explain the result you obtained?
Problem 2: What is the difference between tap water and distilled water? Was there an appreciable difference between the times for the two types of water? What was it (if any) and how do you explain it? Was there any difference in the residue? What was it (if any) and how do you explain it?
Problem 3: Draw Lewis structures for the ff: Alcohol, Water and Olive Oil
Problem 4: Describe each molecule in terms of polarity and presence/absence of hydrogen bonding and length of non-polar portion of the molecule.
Problem 5: What are the types of intermolecular forces?
Problem 6: Compare the boiling points between water and olive oil.
