Highlight the peaks assigned to O-H, C-H and C=C stretching by annotating the spectrum. From the IR spectrum of standard eugenol, the wavenumber shows: 3516cm -1 (O-H stretch), 1637cm -1 (C=C stretch), 1612cm -1, 1513cm -1, 1465cm -1 (aromatic C=C stretch), 1267cm -1, 1234cm -1 (C-O stretch). The IR spectrum of the sample at hand has a clean broad peak at 3530.05 cm-1. The clean peak indicates that it is a pure sample. The broad peak at 3530.05 cm-1 is indicative of a hydroxyl functional group which would signify that the distillate is eugenol and not eugenol acetate. Shown below is the IR spectrum of eugenol. Highlight the peaks assigned to O-H, C-H and C=C stretching by annotating the spectrum.

Figure 2: Eugenol. In addition, the IR of the product from the steam distillation of cloves closely corresponds with that of an authentic sample of eugenol shown in the lab text.9 Therefore, it can be concluded that the oil which was isolated from cloves is in fact, eugenol. 0.0770 g of eugenol was recovered from 1.032 g of cloves.

Nitro groups show two intense peaks in the IR spectrum: one between 1300-1400 cm-1 for the symmetric stretching mode, the other one between 1500-1600 cm-1 for the asymmetric stretching mode. 6. The presence of two peaks in the carbonyl range (1630-1850 cm -1 ) indicates either the presence of an "anhydride type" of function or two different carbonyl functions.
