A student has a mixture of butanoic acid (liquid) and phenol ( ) (solid). The mixture is almost (1:1). The pas for both compounds are 4 -5 and 10 respectively. Both compounds are soluble in ether (organic solvent that is insoluble in water). Select the best technique to separate and recover each compounds. Recrystallization. Use strong basic water as a solvent and recover the solid while leaving the liquid behind. Add acid to recover the butanoic acid. Recrystallization. Use ether...
1)When you perform a liquid-liquid extraction using a separatory funnel, which of the following organic solvent is on the bottom of the aqueous phase and which is on top? (write your answer by the solvent name) a) Ethyl acetate b) hexane c) Dichloromethane d) diethyl ether 2) If you are performing a liquid-liquid extraction and you have a mix of a carboxylic acid and a non-acidic compound, which combination of solvents would you use for the separation? a) dichloromethane/HCI b)...
A mixture of compounds containing dimethylamine, phenol, ammonia, and acetic acid is separated using liquid-liquid extraction as follows: Step 1: Concentrated HCl is added followed by draining the aqueous layer. Step 2: Dilute NaOH is added to the organic layer followed by draining the aqueous layer. Step 3: Concentrated NaOH is added to the organic layer followed by draining the aqueous layer. Which compound would you expect to be extracted into the aqueous layer after the addition of dilute NaOH,...
In my liquid-liquid extraction experiment, I have to explain where the "rest" of my product is. we were given 1.000 gram to start with of one acid and one neutral compound and separated using the liquid liquid extraction. First we added NaOH into the flask and shook it and observe the separation of the two layers. Then I drained them into separate beakers and added HCL to the aqueous layer containing the acidic component and I evaporated the solvent off...
Question 7 (1 point) To extract the reaction product from the aqueous reaction mixture, dichloromethane will be added and liquid-liquid extraction will be carried out. Which layer will be the organic (dichloromethane) layer? The density of dichloromethane is 1.33 g/mL. bottom layer depends on the day the middle layer top layer Question 1 (1 point) What class of compound do you always get if you reduce an aldehyde? O 2º alcohol O carboxylic acid ketone 1° alcohol
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...
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...
