Unformatted text preview: 2 H) and a neutral compound (R-H). You should definitely review fundamental acid/base chemistry and understand the role of the drying agent for both parts. Procedure Follow the procedure for PartA and Part D of the experiment. Of the neutral compounds shown in the Table on p. 34 of Pavia only three are possible in our experiment: fluorene, fluorenone and triphenylmethanol. To Complete the Experiment Determine the mp of your isolated caffeine and report your yield (in grams—you can’t calculate a percent yield for this one) and compare with the amount calculated in the prelab calculation. Identify the neutral compound that was present in your original mixture by its mp. From you recorded weight of the neutral compound calculate the percentage by weight of the material in the original mixture (i.e., something ~ 0.36 g). Version 2.3, 9/15/07...
