Consider the reaction below and answer the question below the reaction. A student performed a synthesis of ethyl 4-aminobenzoate (C) as shown in the reaction above. The student added 1.20 g of 4-aminobenzoic acid and 12.0 mL of ethanol together in the presence of sulfuric acid. The reaction mixture was heated to reflux for a period of 45 minutes.

Case Studies An 18-year-old male high school student who had a 4-year history of diabetes mellitus was brought to the emergency department because of excessive drowsiness, vomiting. and diarrhea. His diabetes had been well controlled with 40 units of NPH insulin daily until several days ago when he developed excessive thirst and polyuria. For the past 3 days, he has also had headaches, myalgia, and a low-grade fever.
