Can anyone identify the major peaks in this IR spectrum that
determine important functional groups? It is supposed to be of
Eugenol (isolated in lab from ground cloves). 
Homework Answers
in this eugenol there four major peaks we can observe
1) -OH peak at 3521 cm-1
2) =C-H stretch 2936 cm-1 around
3) C=C stretch 1637 cm-1 around
4) ether C-O stretch 1366 cm-1 around

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...
