What is Zaitsev’s rule? Give the mechanism for the acid-catalyzed E1 reaction of 2-butanol. Give the mechanism for the base-catalyzed E2 reaction of 2-bromobutane. Draw all possible products. You expect three products from the elimination reaction 2-butanol. What are they? The E2 mechanism is a one-step mechanism. True or False? Explain. Which of these two alcohols would you expect to be more reactive under H3PO4/aqueous conditions? Why? Give the structure of the main product in both cases. 1-phenyl-1-propanol 1 -cyclohexyl-1-propanol...

Post-Lab Questions 1. Give the products from the following reactions Nabi CHOM Nath CH, OH 2. What key IR and NMR absorptions would allow you to determine that the products from the reactions above have been successfully synthesized? Ignore absorption also found in the reactant 3. Nal, usually reacts slowly or not at all with esters. Therefore, LiAlH, is often needed to reduce esters. Why do you think LiAiH, is more reactive than...
