- 15. In organic synthesis, sodium methoxide (NaOCH3) is useful as a strong base and as a nucleophile. Sodium methoxide can easily be prepared by reacting which one of the following with methanol? (Hint: This reaction is seen in the pyrimethamine synthesis.) A) sodium chloride B) sodium sulfate C) sodium hydroxide D) sodium metal E) sodium nitrite 16. The reaction of ferrocene with acetic anhydride to form acetylferrocene and diacetylferrocene is an example of which type of reaction?

Why was it important to have dry equipment that was heated in oven and a drying tube placed on top of the condenser for the above-mentioned reaction? Explain?You are employed as a coop student at the Drug and Alcohol Testing Association of Canada (DATAC) developing analytical tests for sports doping agents. You are asked to prepare a procedure for the extraction of methylphenidate, the active compound in Ritalin, from urine samples (consider them as simple aqueous layers, you do not need to consider other components!). The goal of the procedure is to extract the methylphenidate into an organic layer which will then be evaporated, and the residue will be tested for the drug.Your colleague is helping you develop the urine test. They suggest that the urine should be adjusted to a pH above 7 before extracting with the organic solvent. Why is this necessary? Support your explanation with a full arrow-pushing mechanism for the reaction that would occur if the pH was below 7. Include all formal charges, intermediates (if applicable) and products.

- Pls solve this question correctly in 5 min i will give u like for sure Balance the chemical equation of a reaction formed by the bromination of trans-cinnamic acid if we started with 0.3088 grams of trans cinnamic acid and 1mL of bromine. The product of this reaction is 2,3 - dibromo - 3- phenylpropanoic acidA student use the same protocol as in the lab manual to extract benzoic acid, phenol, and naphthalene. Below are the steps he took Step 1 - Dissolve all three in 15 ml ether and place in separatory funnel Step 2- Add 15 ml of sodium carbonate and mix well Step3 - Isolate the aqueous layer and Add hydrochloric acid, which resulted in a precipitate Step 4- Add 15 ml of sodium hydroxide to the ether layer and mix Step 5- Isolate the aqueous layer and add hydrochloric acid, which resulted in a precipitate. Step 6- dry the ether layer and collect the solid that is leftIn the workup of the grignard reaction of turning bromobenzene to benzoic acid, we start by mixing the grignard with HCl and diethyl ether. We discard the aqueous layer and wash the organic layer with water. Then, the organic layer is extracted with NaOH. Then, the extracts are heated to remove ether. Then, it is precipitated with HCl. Precipitate collected. Let it dry and finally, purified with toluene and hexanes. Please make a flowchart of the process of this workup indicating what products and byproducts are forming. And what compounds are in the aqueous layer and organic layer in the steps.
- please do the mechanism. Identify which one is the nucleophile/electrophile. Name the reaction as well. Discuss the stereochemistry so why the dash bond go to wedged- due to inversion? Why is PPh3 used for selectivity ? Please answer all of my questions.REACTION Acidic conditions REACTION Basic conditions In a round-bottom flask of appropriate size attached over a stirring plate, stir 4-methoxyacetophenone (6.00 mmol) and acetic acid ([ketone] = 0.90 M) until homogeneous. Add bleach (6% m/v NaOCI, 1.60 eq.) slowly, over a few minutes. Allow the mixture to stir at room temperature for 20 minutes, then monitor the reaction by TLC. If starting material can still be found, add a slight excess of bleach (0.10 eq.), stir an additional 10 minutes and check again by TLC. In a round-bottom flask of appropriate size, add sequentially 4-methoxyace- tophenone (3.50 mmol), bleach (6% m/v NaOCI; 6.00 eq) and 3M NAOH (1.00 eq.). Asemble a reflux apparatus, and boil the resulting mixture for approximately 20 minutes. Analyze the reaction by TLC: if the reaction is still ongoing, reflux an additonal 5 minutes before repeating this TLC step. Once over, add ~2 mL of acetone to the mixture through the condenser. Allow the solution to gently boil for…Synthesis of Orange II dye. During vacuum filtration, is it possible to use cold water for rinsing/collecting the Orange II dye? Clearly explain why or why not.
