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...

2. (7 points) The following reactants were supplied to a cell-free extract that included a transaldolase and all of the enzymes of glycolysis. If the sedoheptulose-7-phosphate was labeled as seen below, show the products of the transaldolase reaction and indicate which product would enter glycolysis (hint: only one of the products of the transaldolase reaction enters glycolysis). Make sure the...
