Question

Regioselectivity of E1 and E2 Reactions 3. The reaction between a 1,2-dimethylcyclohexanol and concentrated strong acid results in an E1 reaction. Show the first step in this reaction (consider that the acid catalyst can protonate the OH group which eventually can form H2O that can act as a good leaving group). а. сн, OH conc.H2SO4 CH3 b. What is the geometry at the reaction center of the intermediate? Show the final step and all possible alkene products с. State the rule that determines the major and minor alkene product(s) that form during d. elimination reactions. e. Using the rule from part d, determine the major and minor products. The reaction between cis-1-bromo-2-methylcyclohexane and ethoxide (a very strong base) 4. results in an E2 reaction. (refer to Mechanism 9.8 in your textbook) Show the transition state for this reaction. a. CH3 + CI CH3O- сн CH-он Show the formation of the product(s) from the transition state. b. #
