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. Н.so, cat.) Wear gloves. Methanol is poisonous. Ether is an anesthetic, so don't breathe it. Sulfuric acid is a strong corrosive acid. Wash any you spill...
SYNTHESIS OF T-PENTYL CHLORIDE LAB Provide a stoichiometry table for the reaction being performed in this lab. PROCEDURE Preparation oft-Pentyl Chloride In a 125-mL separatory funnel, place 10.0 mL of tert-pentyl alcohol (2-methyl-2- butanol, MW = 88.2, d = 0.805 g/mL) and 25 mL of concentrated hydrochloric acid (d 1.18 g/mL). Do not stopper the funnel. Gently swirl the mixture in the separa- tory funnel for about 1 minute. After this period of swirling, stopper the separatory funnel and carefully...
Help with PreLab questions 1-4 Procedure Esterification Each group will be assigned an unknown alcohol by the instructor. Record the unknown number and then add the contents of the vial (25 mmol of alcohol) to a 50 mL round bottom flask with a stir bar Then add 2.75 mL (approx. 50 mmol) of acetic acid followed by 0.25 mL of concentrated sulfuric acid Add a reflux condenser then reflux the mixture in a sand bath with stirring for one hour....
Write a mechanism of the synthesis diisobutylene from tert-butyl alcohol with the use of elimination reaction. The following is the procedure of how it was done in the orgo lab: First of all, with the use of graduated cylinder 7mL of water was measured and then transferred in a 50mL round bottom flask. To the round bottom flask, it was added 7mL of sulfuric acid. The mixture was then cooled until the temperature got below 50 °C. In order to...
Place 3.0 g of salicylic acid in a 125-ml Erlenmeyer flask. Carefully add, stirring constantly, 6 mL of acetic anhydride, followed by 10 drops of concentrated sulfuric acid. Swirl the contents of the flask so that the reactants are thoroughly mixed. Stopper the flask with a one- hole cork fitted with an inverted Pasteur pipet to prevent condensation of water in the reaction flask during heating on the steam bath. Heat the flask in a boiling-water or steam bath for...
Thumbs up for good answer. Why does the liquid in the round bottom flask turn light pink?, please explain (This happened during/after step 2). This is the procedure and the experiment is called Synthesis of Artificial Flavorings by Fischer Esterification. Thank you! SAMPLE PROCEDURES: 1. Isoanvl acetate (banana) + H2O OH HO 1. Mix 6 mL of isoamyl alcohol (0.809 g/mL, 88.148 g/mol) and 10 ml ofglacial acetic acid (1.05 g/ml 60.05 g/mol) in a 100 mL round bottom flask....
How can the NMP oxalate salt be converted back to NMP? Here is the procedure: PROCEDURES Part A: Synthesis of (±)-N,N-dimethyl-3-phenyl-3-(4-trifluoromethylphenoxy)propanamine To the 250-mL round-bottom flask (RBF) containing (±)-3-(dimethylamino)-1-phenylpropanol (product from Lab 6) and a magnetic stir bar, add 4 mL of 4-chlorobenzotrifluoride and 30 mL of dimethylacetamide (DMA). With stirring, add to this mixture 30 mL of 1.0 M potassium tert-butoxide (caustic alkali!) in tert-butyl alcohol using a syringe. Using a simple distillation apparatus, distill the mixture slowly, with...
The alcohol could easily be converted to a tosylate, a good leaving group, and a conventional substitution reaction could have been performed instead of the nucleophilic aromatic substitution (NAS) reaction. Why was the NAS reaction the preferred method? (Hint : Look up the nucleophiles of both reactions on chemical manufacturing site.) Part A: Synthesis of (t)-N,N-dimethyl-3-phenyl-3-(4- trifluoromethylphenoxy)propanamine 1. To the 250-mL round-bottom flask (RBF) containing (t)-3-(dimethylamino)-1-phenylpropanol (product from Lab 6) and a magnetic stir bar, add 4 mL of 4-...
Please calculate the percent yield if my actual yield was 0.06g NUCLEOPHILIC DISPLACEMENT- FORMATION OF AN ETHER BY AN SN2 REACTION Bond formation by use of an SN2 reaction is very important for organic and biological synthesis. Many new bonds formed make use of this versatile reaction pathway. In this reaction, one partner is the nucleophile and the other partner is the electrophile. The electrophile will have a leaving group that will be lost in the reaction. In the SN2...
