- How heating affects the synthesis of aspirin? What is the purpose of employing recrystallization in the synthesis of aspirin experiment? Explain how it works. Aspirin undergoes the typical reactions of esters. With this in mind, can aspirin be recrystallized using hot water? Is the product isolated a pure aspirin?An unknown sample is found to be soluble in water. The aqueous solution was found to change blue litmus paper to red and it gave a red precipitate with Benedict’s reagent. How many functional groups are present in this sample and what are their identities? There are two explanations as to why these functional groups are present in this sample. What are these two explanations?What is the reaction for the 2-methylpropan-1-amine(Isobutylamine) titration with hydrochloric acid? Explain how to solve such tasks. Thanks

- In the isolation of caffeine from coffee experiment, the dichloromethane solution was washed with strong base. Explain a possible reason for this.Question 1 You are employed as a co-op 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. You find that methylphenidate is highly soluble in 2-methyltetrahydrofuran, a bio-renewable solvent. Draw the structure of 2-methyltetrahydrofuran and give two reasons why it is a good solvent choice for liquid-liquid extraction. (Please find the image attached below to help you with this question) Question 2 (cont. from scenario 1). Your colleague is helping you develop the urine test. They suggest that the urine should be adjusted to a pH above 7 before…In the experimentation where we oxidize cyclohexanol with bleach (NaOCl).

- Why does a solid form at the interface of the two solutions? PROCEDURESynthesis of NylonIn a small beaker dissolve ~ 0.5 mL of sebacoyl chloride in 12 mL of ether. In a smalltest tube get ~ 6 mL (~1/4 of a 6 “ test tube) of 1,6-diaminohexane solution in water.In order to form the good polymer fibers, it is best to not mix the solutions. Youshould try to layer one solution on top of the other. First pour the 1,6-diaminohexanesolution into a 100 mL beaker. Then slowly pour the sebacoyl chloride down the sideof the tilted beaker with minimal mixing. At this point you should see two distinctlayers with a white film at the interface. Hook the nylon which forms at the interfacewith a straightened paper clip and pull slowly straight up as high as possible. Thenwrap it around your large beaker and then continue to wind the polymer around tillthe reaction is complete. Rinse your polymer in DI water to remove any salts or acidthat may be present.Weigh your product and characterize it by…Why is benzoic acid more soluble in ethanol than in water?Why does β-naphthol dissolve in a basic medium?
