Eugenol acts as an acid, NaOH acts as the base. NaOH strips a proton from eugenol, forming a salt, Na(eugenol(minus)H) and water.
pKa=40
how do you calculate pKa
pKa=2.86
pKa = 15
Eugenol is practically insoluble in water; it is hydrophobic.
Clove oil is a mixture of compounds, but the main ingredient is eugenol, about 70-90%. Eugenol does have an acidic hydrogen, but it's not a compound i would call an acid, the acidic hydrogen is only a small part of the entire molecule. it's pKa, measure of acidity, is about 10, so it's a very weak acid indeed.

Eugenol is a constituent of essential oils (lavender, rosemary, etc.) which are sometimes used to create cologne/perfume. So either the eugenol is just a part of the essential oils used to create the fragrance, or the eugenol is added as a preservative.
pKa = 15
It is around pKa=13
Eugenol is not chiral because it contains no assymmetric carbons. (carbons with 4 different groups attached to it)
NaOH strips the proton from eugenol giving the oxygen on eugenol a negative charge, a sodium cation, and water
Doxofylline Pka value is about 9.8.
