6. A sample of 9.0 mL of cyclohexanol was mixed with 2.0 ml of 85% phosphoric acid and heated. The reaction yielded 4.0 mL of cyclohexene. Calculate percent yield for this reaction. (3 pts.) 7. Provide a detailed mechanism for the reaction 2,2-dimethylcyclohexanol with phosphoric acid. Give the major product and do not forget the charges and arrows. (4 pts.)
5. A common observation test to confirm the presence of an alkene (or unsaturation, in general) is the bromine test. a. What was the observation in the bromine test that allowed you to conclude an alkene was present? (3 pts.) b. Write the equation for the reaction between the major alkene produced and bromine. Be sure to show the correct stereochemistry in the product. (3 pts.) 6. A sample of 9.0 mL of cyclohexanol was mixed with 2.0 ml of...

Click to see additional instructions If you used 12.0 mL of cyclohexanol and 2.5 mL of 85% phosphoric acid for the reaction, what would be your theoretical yield? grams. Enter only the number. Hint: Use 3 significant figures.
1. For the acetylation of ferrocene, ferrocene is mixed with acetic anhydride and 85% phosphoric acid and heated for 20 mins. Why is phosphoric acid used rather than a stronger acid such as sulfuric acid? 2. For the oxidation of ferrocene, NH4[PF6] is added to the reaction mixture of ferrocene, acetone, distilled water, and anhydrous FeCl3. What is the purpose of adding NH4[PF6]?
the reaction is making cyclohexene fron cyclohexanol Write a complete mechanism (hand written) for this reaction. Make sure to include all species involved and all charges. H' by itself does not exist in solution. Since the reaction is done in concentrated phosphoric acid (85% H3PO4), this is the source of H. (3 marks)
6) Ethylene, 15.00 g, is reacted in water, 100.0 mL, and a phosphoric acid catalyst at 250.0°C to give 8.500 g of ethanol. Calculate the percent yield for this reaction?
A 10.00 mL sample of phosphoric acid is titrated with 20.15 mL of a 2.50 mol/L sodium hydroxide solution. H3PO4 (aq) + NaOH ----> H2O (l) + Na3PO4 (aq) a) Balance the molecular equation and write the net ionic equation. b) calculate the molarity of phosphoric acid. c) calculate the mass percent of phosphoric acid in the water mixture (density = 1.50 g/mL)
