1. Make a graph of Boiling Temperature vs. Distillate volume for pure isopropanol and for each of the mixtures.

2. From the graph of pure isopropanol, determine the boiling point.

3. From the distillation curves for the mixtures, determine the volume of distillate at 78C with and without column.

4. According to the results obtained in question # 3, indicate which method is more efficient. explain.

5. Write two examples for a secondary alcohol and two for a tertiary alcohol, including at least one cyclic structure for both types of alcohol.
