How would you separate compounds A, B, C and D below and they
were mixed using an extraction experiment. Assume the compounds are
soluble in dichloromethane and you have at your disposal HCl, NaOH,
NaHCO3. Show your answer in a form of flow chart and include all
steps including which layer is which.

Provide a flow chart detailing the acid/base extraction/separation of the compounds show below. Your answer must employ the following reagents: methylene chloride, hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M), 10% sodium bicarbonate (aq). Clearly indicate the product(s) and layers formed following each step of your separation scheme. IMPORTANT: p-cresol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. 2-ethylbenzoic acid is soluble in both sodium hydroxide and sodium bicarbonate solutions.

Complete the flow chart below to illustrate how you would separate and isolate (as dry uncharged solids) the compounds shown below. Draw the structures of the compounds present in each layer and in their correct form (i.e. charged or uncharged) in the boxes provided. Each box is 3 points. For steps (a), (b) and (c) use only the reagents and/or terms provided in the word bank at the bottom of the page (you may not need all of the lines....
You will have to perform all the steps necessary to separate your assigned compound from its impurities and prove through analysis (melting point, boiling point (if applicable), NMR, IR and Rf-values (if applicable)) that your compound is pure: An organic student was trying to purify acetaminophen from Advil but the extraction using dichloromethane yielded a mixture of caffeine and acetaminophen. Purify the acetaminophen. Provide data to show that your compound is pure. Materials Available to you: Solvents: acetone, ethanol, methanol,...

Acid/Base Extraction
1. Provide a flow chart detailing the acid/base
extraction/separation of the compounds shown below. Your answer
must employ the following reagents: methylene chloride,
hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M),
10% sodium bicarbonate (aq). Clearly indicate the product(s) and
layers formed following each step of your separation scheme.
IMPORTANT: p-cresol is soluble in sodium hydroxide solution but
insoluble in neutral water or sodium bicarbonate solution. 2-

A mixture containing 1, 3, 5-trimcthoxybcnzcnc (A), phenol (B), aniline (C) and 1-naphthoic acid (D) was dissolved in dichloromethane. Next two extractions were performed first using HC1 then with NaOH. Which of the compounds could not be separated in this procedure. Explain and show the pertinent reaction equation/s. student wanted to separate a mixture of benzoic acid and aniline that were dissolved in ethanol. Could the student separate the two compounds using a base extraction (NaOH)? Explain
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!

Construct a flow chart that follows the separation of a mixture
of 2-nitrophenol (an organic acid not used in this experiment with
a pKa = 7.26) and anthracene (neutral organic). Use scheme 1 as a
template. Your reagents available are the same ones used in this
lab.
