5. For today's experiment, you will be performing the first step of your multistep synthesis to make trans- 1,2-cyclohexanol from hexanol. You will be using distillation to separate the product of the first step in the synthesis. (see the procedure below for diagrams and photos of what distillation setup looks like. Check the boiling points provided in the chemical table for starting material and product. Which compound boils at a lower boiling point? Explain briefly based on boiling point differences...
