Chemistry 322 Experiment #3 Data Sheet NAME: ________________________________________________ 1. Retention Times (in minutes) of Alkenes in Product Mixtures 2. Relative Peak Areas of Alkenes in Product Mixtures SECTION: ________ 3. Write a mechanism for the dehydration of 3-methyl-3-pentanol and indicate which products are major and which are minor isomers. 4. Flow Chart. Fill in the empty rectangles with the appropriate cations. In the empty ovals, fill in the appropriate methylpentene structures. H+ OH 80-100 oC 80-100 oC (E and Z) 5. In the first part of this experiment, you performed Lucas tests on several alcohols. a) Write a complete mechanism for the reaction occurring between the Lucas reagent and tbutanol. b) Benzyl alcohol and 1-butanol are both primary alcohols, yet they behave differently under Lucas test conditions. Clearly explain the difference in reactivity between these two alcohols. It is NOT enough to say that "X is more stable than Y" - you have to explain why! 6. A small amount of 3-methyl-2-pentene can form during the dehydration of 2-methyl-3pentanol. Write a reaction mechanism that accounts for this product. Consult your lab manual for guidance.
