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...

Experiment Questions What is an epoxide and how is it useful with respect to synthesis design? • What are typical reagents used for epoxidation? • What is the mechanism for epoxidation? Must stereospecificity be considered? Experiment Techniques • Use of sodium bisulfite wash to remove excess peroxy acid from reaction mixture. Introduction By now you are well aware that the product of previous experiment (reaction of cyclohexanol and acid) is an alkene. You should also be storing key reactions of...

Please help with the pre- lab exercise and questions 10 and 11
Experiment 19 Heat of Combustion: Magnesium 18, you learned about the additivity of reaction beats as you confirmed Hess's Law, In this experiment, you will use this principle as you determine a heat of reaction that would be difficult to obtain by direct measurement-the heat of combustion of magnesium ribbon. The reaction is represented by the equation This equation can be obtained by combining equations (1). (2), and...

3. (4 pts) The key step involves a base pulling off one of the benzylic hydrogens in the starting material. Given that the pk of an alkane hydrogen is > 50 and the pk, of a benzylic hydrogen is < 40, explain why potassium hydroxide can be used instead of sodium amide to synthesize 1,2-diphenylethyne from a vicinal dibromide. 4.
