The mass of diol used for your S_N1 reaction was 0.243 g.

The mass of recrystallized product you obtained for your S_N1 reaction was 0.119 g.

The mass of sodium bromide used for your S_N2 reaction was 1.488 g.

The mass of 1-bromobutane you obtained from your S_N2 reaction was 0.586 g.

1. For each of the experiments (S_N1 synthesis of 2,5-dichloro-2,5-dimethylhexane, and S_N2 synthesis of 1-bromobutane), balance the reaction equation.

2. Complete data tables for the S_N1 an S_N2 reactions, using the solid masses assigned to you by the zero-point quiz. Show your work for all calculations required.

For S_N1, use 2.0 mL of hydrochloric acid.

For S_N2, use 1.0 mL of sulfuric acid, 1.2 mL of water, and 1.000 mL of 1-butanol.

3. Using the values you calculated for your tables, plus the masses of product you were assigned by the zero-point quiz, calculate the percent yield for each reaction. Show your work.

4. For each product, predict the result of a) a Finkelstein test, and b) a silver nitrate test. Explain your reasoning.

5. It's important in a lab to avoid cross-contamination of reagents. Imagine that a Pasteur pipette that was used for hydrochloric acid was then used for performing the Finkelstein test. Anticipate whether this might cause a false-negative or a false-positive test. Show your reasoning. Similarly, predict whether this contaminated pipette would cause a false-positive or a false-negative result for the silver nitrate test.
