using the test that you carried out in isolation of eugenol from cloves, describe how you could distinguis between the following pair of compounds.
Cyclohexane and cyclo hexene.
because eugenol is insoluble in water, both eugenol and water co-distill in a process called steam distillation. In steam distillation, the boiling point of the distillate is below the boiling point of either component.
a. Predict the boiling point temperature that would be observed for a compound that has the same boiling point as eugenol but is soluble in water assuming that there is much more water present.
b. predict the boiling temperature that would be observed for a compound that has the same boiling point as eugenol but is soluble in water, assuming that there is much less water present than the other compound.
