Organic Chemistry Nitration lab. 1. Aromatic nitration requires the use of the HNO3 / H2SO4 mixture. Why not use HNO3 alone? 2. Why should the cold nitration reaction be maintained at all times? 3. What difference should be observed between the 1 H NMR spectrum of the nitrated reagent and the product obtained? Explain 4. If the yield percentages for acetanilide nitration products were: 35% o-nitroacetanilide and 65% p-nitroacetanilide, explain how you would perform the procedure to separate and recover...
