31. The reaction of 1,1-dimethylpropanol (tert-pentanol) with a strong acid yieids 2-methyl-2-butene. a) Identify and draw the mechanism of this iransformation. b) Explain how you could use IR spectroscopy to determine if your reaction was successfur? Which characteristic bands would you expect for the starting material, which tor the product? c) Decide based on below 1 H.NMR spectrum, If it depicts the starting material or product and assign all resonances (signals) to respective protons. Hint: Mind the scate on the X-axis
