Theoretical and Percent Yield

Practice Problem

In the following reaction, 0.157g of p-acetaminophenol was used to react with 0.486 g of acetic anhydride to produce acetaminophen and acetic acid.  The product was purified and acetimophen was extracted.  The actual mass of acetaminophen produced was 0.198 g.  Determine the theoretical yield and the percent yield of isopentyl acetate.

p-Aminophenol     +     Acetic anhydride          Acetaminophen         Acetic acid

    C6H7NO                                 C4H6O3                    C8H9NO2                  CH3COOH
