1. (6 pts) These are some of the preliminary tests that you will be doing on days 1-2. For each test, write down what type of molecule would give a positive test and what a positive result would look like. DNP: Solubility Beilstein: Ignition: 2. (2 pts) For the 2,4-dinitrophenylhydrazine test, write a chemical reaction between that reagent and one of the "known" compounds that would give a positive result. 17

LFER = Linear free energy relationship
6. (2 pts) During project 2, you determined whether a LFER existed between the chemical shift value of the N H proton and substituent effects at X in the molecule below. The same experiment could be repeated, but instead varying substituents at Y. Assuming a LFER still exists in this case, predict the sign of p, and predict whether its magnitude would be greater than or less than ρ when X was varied. Give...
