Calculate the number of moles of cyclobexanol used in your experiment Show/write your calculations. Use the volume and density to find the grams, and then molar mass to find the number of moles 2. Calculate the number of moles of sulfuric acid used in your experiment. Show/write your calculatious Use the volume and molarity to find the number of males 3. Calculate the theoretical yield of cyclohexene, based on the amount used in your experiment Determine which of the two (cyclohexanol or sulfanc acid) is the limiting reagent Then, determine the number of moles of product (cyclohexene) based on the LR. Finally, calculate the theoretical yield in grams and then in ml of cyclohexene (use its density) 4.

If either the percent yield or percent recovery is less than 60% discuss possible reasons for the low yield/recovery. and suggest improvements that a chemist could make to the synthesis to increase the yield or recovery. 2) Interpret the NMR results in terms of purity. What should a chemist do to improve the yield or purity of the product? Discuss the key parts of the NMR for the starting material and pure product. Focus on the peaks that show up after 3 ppm. For the starting material, discuss what those 2 peaks (around 3.5 ppm and 4.7 ppm) correspond to in the structure of cyclohexanol For the pure product, discuss why those 2 peaks are missing, and there is a new peak for 2H at around 5.6 ppo Then, discuss the NMR for your actual product from the reaction. Does it contain pure product? If not, what else is there? How do you know this based on the NMR? Based on your understanding of the reaction and LeChatelier's principle, how can you improve the reaction yield? How can you better purify the reaction product? dictions On Accessibility: Investigate Q Search 4) 34 F4 DII NC F5 F6 * % 95 PrtScn F7 Home P9 Enci F30 Λ <6 & 7 * 8 9
