1. 2-Pentanone and valeraldehyde base close boiling points, 102 and 103 ⁰ respectively. Suggest a way that these two compounds could be distinguished and identified. (A boiling point difference of 1 ⁰ C is too close to measure experimentally.)

2. Use laboratory tests from this experiment and show how you could distinguish between the compounds listed below. Suggest tests that give a clear, positive test result for the listed compound but are unique to it and thus, different from the others.
