Explain the acid/base chemistry that occurred when you separated the organic base and neutral compound. Include chemical equations.
The two compounds used were 1,4-dichlorobenzene and ethyl 4-aminobenzoate.
Homework Answers
4-amino methyl benzoate is basic compound so soluble in Acid HCl.
Both compounds are soluble in ether and form homogeneous mixture. To this add aqeous HCl solution. Then two layers are formed one is aqueous and other is organic layer.
Organic layer have 1,4-chloro benzne and aqueous layer has ethyl 4-amino benzoate.

You will apply what you have learned earlier in the semester when performing the Acid-Base Extraction experiment to perform a different separation: that of an organic neutral compound and organic base. You will also need to purify and characterize these compounds. You will have one lab period to execute your plan for separating the assigned mixture given below. There will be a 1:1 (by mass) mixture placed in the lab: 1,4-dichlorobenzene/ethyl 4-aminobenzoate. You will take approximately 1 g of your...

I need help calculating total percent recovery. I have to get the percent recovery for the two compounds I separated during an organic base and neutral compound extraction experiment. The lab started with 0.6 g of a 1:1 mixture (by mass) of 1,4-dichlorobenzene/ethyl 4-aminobenzoate. My two compounds are 1) 1,4-dichlorobenzene in 95% ethanol and 2) ethyl 4-aminobenzoate in hot 95% ethanol. These are my results: 1,4-dichlorobenzene recovered 0.329 g ethyl 4-aminobenzoate recovered 0.271 g Please show all work on how...

The Separation of Three Organic Compounds by Acid, Base Reactions and Liquid, Liquid Extraction. Okay, so we had solid benzoic acid, ethyl 4- aminobenzoate, and 9-fluorenone all dissolved in methyleene chloride. We separated the basic component by adding 3M HCl, we separated the acidic component by adding 3M NaOH. I don't understand what happens here. To isolate the acidic solution, we added 6 M NaOH and used the vacuum to recover the solid. To isolate the basic solution we added...
