1. Draw out the structures to show the dehydration reaction for cyclohexanol. 2. What is the purpose of the phosphoric acid in the experiment? 3. In the first distillation, at what temperature does the cyclohexene separate from the reaction mixture? Why does cyclohexene come over at this temperature? Why doesn't the cyclohexanol come over? 4. What is present in the sample after the first distillation? 5. Explain how the cyclohexanol and water are removed from the cyclohexene in the solvent extraction step.
