For clarity, make sure any time you separate two layers, you label the fractions if you need to refer back to that fraction. For instance, "the layers were separated, Aqueous = "Fraction D", organic = "Fraction E". Fraction D was placed back in the separatory funnel..." This is best because throughout your procedure, you will separate the "organic layer" several times, so you can't just call it 'the organic layer'. c. At the end, write down which organic fractions contain which material.

Question
2. Devise an acid/base extraction method capable of separating Eugenol from
caffeine. The pKa of eugenol is about 10 and the pKa of caffeine--HCl salt
(caffeine's conjugate acid) is also about 10.
a. Give me a brief overview of how it might be done.
b. Give a concise, full procedure for the method. The goal is to have one organic
solution that contains pure Eugenol and another organic fraction that
contains pure e caffeine. Use drawings if this will limit the number of words
and make it more clear. For clarity, make sure any time you separate two
layers, you label the fractions if you need to refer back to that fraction. For
instance, "the layers were separated, Aqueous = "Fraction D", organic=
"Fraction E". Fraction D was placed back in the separatory funnel..." This is
best because throughout your procedure, you will separate the "organic
layer" several times, so you can't just call it 'the organic layer'.
c. At the end, write down which organic fractions contain which material.
