1. Calculate the percent yield of alkenes in your dehydration. (HINT: What role does the sulfuric acid play?) 2. Calculate the retention time for each peak in your chromatogram. Retention time is elapsed between the injection of the sample and the defined as the time appearance of the top of the peak. 3. Which peak in your chromatogram of your sample corresponds to 2-methyl-1- methyl-2-butene? Explain how you made these decisions. 4. Calculate the mole fraction of each alkene as follows: butene? To 2- a. Measure the height of each peak. b. Assume that mole fractions are directly proportional to peak heights.
