The Separation of Three Organic Compounds by Acid, BaseReactions and Liquid, Liquid Extraction.
Okay, so we had solid benzoic acid, ethyl 4- aminobenzoate, and9-fluorenone all dissolved in diethyl ether. We separated the basiccomponent by adding 3M HCl, we separated the acidic component byadding 3M NaOH. I don't understand what happens here. To isolatethe acidic solution, we added 6 M NaOH and used the vacuum torecover the solid. To isolate the basic solution we added 6M HCl. Idid an experiment where a 1:1:1 mixture of Benzoic Acid solid(C6H5COOH), ethyl 4-aminobenzoate solid (C9H11NO2), and9-fluorenone solid (C13H8O) was dissolved with methylene chloride.Then each component was extracted and tested. I need to come upwith a proton transfer chemical reaction that represents whathappened in each separation. First separation: HCl was added andtwo layers formed. aqueous layer was extracted and transfer to aclean container and methylene chlotide layer was left aside. NaOHwas added dropwise to aqueouse layer extraction and vacuumfiltration was used to extract/separate the basic component ethyl4-aminobenzoate solid (C9H11NO2).

I need to find the theoretical and percent yield of eachproduct, how many mg of each product is present. And also create 4chemical reactions. Need help, Please help thankyou
