If methylene chloride was used as the organic solvent in solvent extraction, instead of ether, what would the top layer be in the separation step? This is in reference to a Solvent Extraction experiment.
methylene chloride is an organic solvent.
It is having density more than water (aqueous layer).
Therefore, the top layer will be aqueous layer and the bottom will be methylene chloride layer with an organic compound.
If ether used. then the top layer will be ether and the bottom layer will be aqueous.
methylene chloride ether
top layer - aqueous top layer - ether
bottom layer - methylene chloride bottom layer - aqueous

forming an extraction, which organic solvent is expected to be the bottom layer? 13. When performing an extractic (1 pt) A. Toluene-CyH8 B. Ethyl acetate -CH:CO,CHs C. Methylene chloride - CH2Cl2 D. None of the above-the organic solvent is always the layer on top. 14. Provide the mechanism for this reaction. (5 pts) HB:

Prelab
1. Explain in a few sentences how extraction can be used to separate an organic compound from
sodium chloride.
2. Why is the CH2Cl2 layer the bottom layer in a CH2Cl2 / aqueous NaHCO3 extraction? In this
experiment, what does the CH2Cl2 layer contain? What does the aqueous NaHCO3 layer
contain?
3. In general, how...
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-
ethylbenzoic acid is soluble in both sodium hydroxide and...
If the Partition Coefficient for Benzoic Acid in one mL each of Water and Methylene Chloride is 2.10, is there more Benzoic Acid in the Water layer or the Methylene Chloride layer? A) If you have one mL each of Water and Methylene Chloride in a vial, which layer is on the top? B) If the same experiment is repeated with benzoic acid between ether and water, which layer would be the top and which layer would be the bottom....
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 diethyl ether. 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...
Extraction Q1. Why doesn’t the neutral organic compound dissolve in the 1.5 M NaOH solution? Q2. Why is diethyl ether a good choice for the organic solvent in this extraction experiment? Q3. What experimental difficulty would you encounter if you neglected to include the drying step before evaporating the ether solution of the neutral organic compound? Q4. Why are the two organic compounds recrystallized before their melting points are determined? Q5. What IR bands are most useful in distinguishing a...
Part A 1. If you had used more methylene chloride in each step, you could have extracted more caffeine. Explain why you did not. Hint - What step would have taken longer (Hint: not drying).
