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