Name_____________________________Directions: Please answer the following questions and exercises correctly.
1. The balanced reaction for the acetylation of salicylic acid is shown above. The products are aspirin (acetylsalicylic acid) and acetic acid. (a) Determine the theoretical yield and of aspirin for this reaction if you begin with 2.54 g of salicylic acid and 6.8 mL of acetic anhydride. (b) Determine the percent yield if you obtained 1.97 g of aspirin as your final product. SHOW ALL YOUR WORK!!!! 2. Which of the three circled functional groups of salicylic acid shown below will give rise to a positive ferric chloride test?
3. Can you suggest one reason why the MP of aspirin is lower than that of salicylic acid? Please explain_1315656281.unknown
