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...

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!

Please help answer P1-P4 for this Perkin Reaction Lab
Perkin Reaction Organic REActivity PERKIN REACTION (ALDOL CONDENSATION) The Reaction Scheme: Formation of trans-cinnamic acid The following reaction is named the Perkin Reaction. It is a very specific type of Aldol condensation that forms a variety of cinnamic acid derivatives. In this lab, you will perform a Perkin reaction using benzaldehyde and potassium carbonate in acetic anhydride to form trans- cinnamic acid (1). Trans-cinnamic acid is a natural compound found in...
