4. In this experiment, ethanol was selected to purify benzoin on Day 1. However, alcohols are inappropriate solvents for recrystallizing compounds containing carboxylic acids. One side reaction is "Esterification" that can occur by placing COOH and OH groups together upon heating. If 3.5 grams of Terephthalic acid and 3 mL methanol undergo esterification, (a) what is the limiting reagent? (b) Predict the grams of the two end products: dimethyl terephthalate and water assuming Esterification is driven to completion. Show calculations. Hint: you can find the grams of methanol through its density.

Asprin can be made in the laboratory by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form asprin (C9H8O4) and acetic acid (C2H4O2). The balanced equation is: C4H6O3 + C7H6O3 ------> C9H8O4 + C2H4O2 In a laboratory synthesis, a student begins with 5.00 mL of acetic anhydride (density = 1.08 g/mL) and 2.08g of salicylic acid. Once the reaction is complete, the student collects 2.06g of asprin. determine the theoretical yield of asprin for the reaction
