POST-LAB QUESTIONS Calculate the percent (by mass) of eugenol in cloves based on your data. Eugenol typically makes up about 15-20% of the mass of clove buds. Discuss reasons why you may not have isolated this amount, and propose ways to increase your yield. 1. ES 2. Examine the IR spectrum of eugenol, and identify the signals for the major func- tional groups. A representative 'H NMR spectrum of eugenol is shown below. Assign the signals to the correct protons in the structure. 3. Eugenol OH 3H OCH3 3H 2H 2H 1H 1H 2 6 10 PPM Eugenol can also be isolated from cloves using extraction with CO. Discuss the ad- vantages and disadvantages of distillation versus 4. CO, extraction -CO
