1. Which IMF or IMFs are correlated with molar mass? Describe this correlation
2. Heptane, hexane, and pentane are hydrocarbons. Rationalize the evaporation data of these substances based the type(s) of IMFs present in each and the relative strengths of these.
3. Ethanol, methanol, 1-propanol, and 2-propanol are alcohols. Rationalize the evaporation data of these substances based the type(s) of IMFs present in each and the relative strengths of these. (Hint: How are these molecules alike and how are they different?)
4. 1-propanol and 2-propanol are isomers, substances having the same chemical formula. Is the evaporation data for these substances the same or different? If different, can you account for why this may be the case from a comparison of the Lewis structures of each substance and the IMFs present in each substance? Explain.
5. Acetone and 2-propanol are chemically interconvertible. Reduction (by the addition of the equivalent of H2) of acetone yields 2-propanol. Conversely, oxidation (by the removal of the equivalent of H2) of 2-propanol yields acetone.
Is the evaporation data for these substances the same or different? If different, can you account for why this may be the case from a comparison of the Lewis structures of each substance and the IMFs present in each substance? Explain.
6. Examine the evaporation data for ethanol, acetone, hexane, and pentane. Is this data consistent with your expectations based on the types of IMFs present in each substance? Explain.
