4-aminophenol (1.0 g) was dissolved in an inert organic solvent. Pyridine (1.50 mL) and acetyl chloride (1.40 mL) were added, and the reaction was stirred until determined to be complete by TLC. Afteworkupup and purification, you isolated 1.40 g of a product. The experimental melting point was 155 oC, and mass spec analysis indicated that the molecular weight of this product is 193.20 g mol─1. What is the structure of the isolated product? Suggest a specific procedural modification that would...
A similar pain reliever to aspirin is acetaminophen, which can be synthesized following a similar reaction scheme seen below. - H₂C H₂C HO NH. MH =0 + o + -cн, но p-Aminophenol нас Acetic anhydride Acetaminophen Acetic Acid a. If 2.00g of p-Aminophenol ( 109.1 g/mol) reacts with 5.00 mL of acetic anhydride (102.1 g/mol and density - 1.08 g/mL), what mass of acetaminophen (180.2 g/mol) would be made? Show all calculations. Mass of acetaminophen: b. If you only isolated...
Using chemical structures, write out a balanced chemical reaction for the synthesis of acetaminophen from 4-aminophenol and acetic anhydride. Please make your drawing clear and label everything thanks.
1) Which reactant, salicylic acid or acetic anhydride, is in excess? Show your work. 2) If you were to use 3.17 g of starting material, how much product would you expect? Again, show your work. 3) Why is phosphoric acid added to the reaction? 4) A small amount of water is added at the end of the reaction to react with the excess acetic anhydride. Show a balanced equation for that reaction. 5) Explain the purpose of the FeCl3 test...
Name Lab Partner LAB 9 REFLECTIVE EXERCISES Lab Section 1 What data did you collect to indicate that you successfully produced aspirin? What did your results indicate about the purity of the aspirin you obtained? Explain your answers. 2 Given that the melting point of salicylic acid is 159 C, can you be certain that the product you isolated was not pure solicylic acid that was unchanged during the reaction? Can you be certain that the product you isolated was...
4. Based on the mole ratio of the reaction (1:1 for the reactants), determine which reactant is the limiting reagent, based on the amounts you will be using as shown under “Reagents” above. Show your work. (Note: the density for the acetic anhydride solution is 1.08 g/mL) The amounts for p-aminophenol is 1.5 g, and the amounts for acetic anhydride is 2.5 g in 7.5 mL of water. The molar mass of p-aminophenol is 109.14 g/mol. The molar mass for...
Suppose you started with 25.8 g of salicylic acid and an excess of acetic anhydride was used to synthesize aspirin. If you obtained 21.7 g of aspirin, calculate the yield of this reaction. (Show your detailed calculations) (1.5 Points) 3. After carrying out the aspirin synthesis experiment, suggest two experiments or techniques (give only name of Experiment) based on what you have learned last few weeks to confirm the preparation and purity of aspirin. (1 Point) 4. A commercial aspirin...
Question- The second step is a name reaction. a) What is its name: b) Is it OK that we left the reaction in our drawer over the week? What would have happened if we didn’t have a good seal on the stopper? Draw a possible reaction scheme. Background The field of medicinal chemistry combines the specialties of synthetic organic chemistry and biology, and biochemistry. Compounds are generated and biological activity is screened using target specific assays. . These assays are...
