Eugenol is the component responsible for the odor of cloves, which are dried flower buds of the
evergreen tropical tree Eugenia aromatica. The isolation of eugenol from the rest of the constituents of
"oil of cloves" (comprising around 10% of acetyleugenol and caryophyllene) is highly dependent on the
chemically active proton of the phenolic group of eugenol. Draw the structure of the main components
of "oil of cloves" and describe how to isolate or extract eugenol considering its structure.
