In lab we extracted benzoic acid and fluorine in a mixture with diethyl ether. I understand how benzoic acid was extracted using NaOH and then HCL but I am confuses how the fluorine was extracted once the NaOH and saturated Nacl was added. What kind of mechanism/reaction occurred that allowed extraction to occur?

Answer #1

Answer:

To the Diethyl ether dissolved Benzoic acid and Fluorine mixture NaOH solution added. The Benzoic acid reacts with the NaOH and forms as a Sodium Benzoate salt.

The acidification of the sodium benzoate salt it becomes the free acid.

If I have a mixture of 2 of the following 3 organic components dissolved in diethyl ether, how do I determine which are present in the mixture. The components are: Benzoic acid, 0.20 M Ethyl-4-aminobenzoate, 0.20 M Acetanilide, 0.20 M I will have ~20 mL of the diethyl ether solution. Additionally, I will have 10% HCl 6 M HCl, 10% NaOH, 6M NaOH, saturated NaCl, and drying agent. Thank you!

The substances given are 50% benzoic acid, 40% benzoin, and 10%1,4-dibromobenzene. I need a seperation scheme, i know i have to use extraction and recrytallization to seperate each. I am just confused which substances to use, the solvents available are water, 1.0M NaOH, 6.0m NaOH, 1.0M HCl, 6.0M HCl, 1M NaHCO3, saturated aq sodium chloride, dichloromethane, diethyl ether, 95% ethanol, methanol, isopropyl alcohol, acetone, hexane, and toluene. thank you for any help!

Organic Chemictry Lab Post Lab Questions (Acid-Base Extraction) 1.) In this experiment, if the carboxylic acid is benzoic acid, how many moles of benzoic acid are present (assume an equal portion of each component)? How many moles of sodium bicarbonate are contained in 1 mL of a saturated aqueous sodium bicarbonate. Is the amount of sodium bicarbonate sufficient to react with all of the benzoic acid? 2.) To isolate the benzoic acid from the bicarbonate solution, the bicarbonate solution is...

ORGANIC CHEMISTRY You have 0.10 g benzoic acid and you add 2.0ml of diethyl ether, then you add 1.0ml of 5% NaOH. If you want to get rid completly of any water molecules, you first add 1.0 mL of NaCl, and after you add a small amounth of anhydrous sodium sulfate (drying agent). Show complete chemical reactions with arrow formalisms for both reactions with NaCl and Na2SO4.

*Explain how the products were extracted with acid and base (explaining solubility in particular layers)* Phenyl acetate was reacted with anhydrous aluminium chloride. As soon as the HCl evolution subsided, the flask was heated for 1 hour. The flask was then allowed to cool and 100g of ice and 15ml of HCl was added. The mixture was then extracted with three 20ml portions of ether. The ether extracts were combined and the phenolic materials were extracted with two 50ml portions...

Question regarding an extraction lab involving benzoic acid, azobenzene, and m-nitroaniline and adding NaOH, HCl, and saturated sodium chloride solution all using a separatory funnel. Why do we need to add the drying agent to the organic layer? What are you removing? Why do we need to add acid to the carboxylic acid flask? Why do we add base to the amine flask? What are we precipitating? How do you improve the purity of the recovered solids?
