Four liquids, A, B, C and D are spotted onto a plate and set aside. A evaporates away immediately. B and C take about half an hour to evaporate away. At the end of the lab period, D is still not evaporated away. Answer the following questions about liquids A, B, C and D.
1. Which molecule (A, B, C or D) is most likely nonpolar?
2. Which molecule (A, B, C or D) is most likely able to form H-bonds?
3. Which molecule (A, B, C or D) would probably have the highest boiling point?
4. If all of the molecules are nonpolar, which one (A, B, C or D) is likely the largest molecule?
5. Which molecule (A, B, C or D) exhibits the weakest intermolecular forces?
6. Which molecule (A, B, C or D) has the strongest surface tension?
