can you pleas help me making a Flow chart for separation a
mixture of trans-cinnamic acid,
4-phenylphenol, and nicotinamide by extraction?
thank you
Procedure Your mission is to separate a mixture of trans-cinnamic acid, 4-phenylphenol, and nicotinamide by extraction. Start by dissolving/suspending two grams of the mixture in approximately 50 mL of diethyl ether. (Caution: Diethyl ether is extremely flammable! Extract the ether twice with -25 mL of 5% HCl and then twice with -25 mL 5% sodium bicarbonate. It...

reaction mixture for 30 min, stirring the mixture rapidly during the process. The start of the reaction is indicated by a slight turbidity of the solution. The mixture may become more turbid as the reaction proceeds and eventually may turn a pale yellow. Allow the reaction mixture to cool to room temperature after the reflux period. Reaction of the Grignard reagent with CO2 :O MgX 1) CO2 (s) 2) HCI OH MgX) magnesium carboxylate complex Grignard reagent substituted benzoic acid...

using the procedures, we used dichloromethane as the unknown
mixture and i was able to extract benzoic acid for an acid,
5-chloro-2-methoxyanaline for a base compound and biphenyl for
neutral compound.
i don't know if that answers the missing part but if it didn't
could you be specific please? thank you!

I understand that equivalents is the ratio of the # of moles
of a reactant or reagent compared to the # of moles of the
substrate. But I am confused on how to answer this question and why
the procedure would call for more NaI than Vanillin if Vanillin is
the substance needed substituted. Can you help?
Thanks!
