1. The reaction mixture contains isopentyl acetate, isopentyl alcohol, water, acetic acid and sulfuric acid. a) Why is the reaction mixture extracted with sodium bicarbonate? In other words, what two substances does sodium bicarbonate react with in the reaction mixture and why are these reactions useful? (4 pts) b) Write a balanced chemical equation for each reaction involving sodium bicarbonate. c) When the reaction mixture is extracted with sodium bicarbonate solution, what substances will be in the aqueous layer? What...

what is the purpose of each of the extractions (washings) the crude product? In other word, what is removed upon washing with (a) water (b) sodium bicarbonate and finally (c) ammonium chloride. The experiment I did is amide synthesis from carboxylic acid and amine and using EDCl with catalyst DMAP and DMF. By doing the extraction. I dilute my reaction mixture with 40 ml of water, pour the contents into separatory funnel. Then add approximately 20 mL of ethyl acetate...

9. Then add slowly while mixing 1 mL of saturated sodium bicarbonate solution (NaHCO3) -IT WILL BUBBLE! Add additional drops of saturated sodium bicarbonate solution with mixing until no additional bubbling occurs Congratulations! You have just made your first ester. Now you want to separate your ester product from the other stuff in the reaction mixture. CTQ3 Sodium bicarbonate is a base. How will it interact with any carboxylic acid molecules still present in your reaction mixture? 10. Add 1mL...

Why did you wash the ether solution with sodium bicarbonate? Write chemical equations for the reactions that took place. b. At which purification steps was the unreacted methanol removed in the reaction? Some of it may have been removed in more than one place. c. Three-Step Synthesis of Methyl Anisate (Step 3) 0 CHOH.

Create a separation scheme flow chart/diagram to isolate methyl salicylate from a product mixture containing the following: Methyl salicylate, methanol, concentrated sulfuric acid. Lab procedure for separation: Extract with 25mL dichloromethane. Drain the bottom organic layer into a beaker. Repeat the extraction with another 25mL portion of dichloromethane, isolate the bottom layer, and then combine it with the first dichloromethane extract. Pour the combined extracts back into the funnel and wash the solution with 25mL of water. Drain the lower...

2. If one were esterifying an expensive alcohol with an expensive carboxylic acid derivative, would it be wiser to use the acid chloride or acid anhydride reagent? Why? 3. Why is so much NaOH used in the extraction? Recall that only four drops (small amount) of sulfuric acid were used as a catalyst. Esters are an important class of organic molecules, which are formally derived from alcohols and carboxylic acids. Esters occur widely in nature and are often an important...
