- Write out a detailed, arrow-pushing mechanism for the DCC- mediated coupling of acetic acid and ethylamineA student was given from the list of the compounds below A, B and D blindly and asked to identify them all. He treated each of them with Brady's reagent (2,4-ditrophenylhydrazine) and isolated a bright yellow compound for one of them, but the other two gave false negatives. The student reasoned that the false negatives may be due to sterics and, on further thinking, it dawned on him that he might be able to rule out one of the false negatives with the haloform test. What compound did he find compatible with the haloform test? That compound did indeed give a false negative in the Brady test. Which of the other two was positive in the Brady test? A = haloform B = Brady A = haloform D = Brady B = haloform A = Brady B = haloform D = Brady D = haloform A = Brady D = haloform B = BradyQ1: Give one lysis buffer that is commonly used for western blotting experiments and include its components Q3: To make sure that you used a similar amount of samples, what important step should be done before proceeding the electrophoresis stage? Q4. Why is it necessary to store the prepared lysates in a very low temperature?
- For extraction with ethyl-4-aminobenzoate and naphthalene using dichloromethane as the solvent, how does one separate the two compounds from one another?Outline a method (based on this experiment) for how you would separate a solution of the three molecules above in ethyl acetate. (Hint: you might need to search their pKa values!) Explain your rationale. You do not need to provide the level of detail shown in the Experimental; just the basics will be sufficient (e.g. wash with _____ to separate component ___, then wash with _____ to separate component Y, etc.). You can write in paragraph style or organize your steps in a numbered list.Can you solve all the parts to this question Answer the following questions about the procedure: A. What would be the optical reading of (+/-)-phenylsuccinic acid (racemic phenylsuccinic acid)? B. What would you expect to be the optical reading of pure (+)-phenylsuccinic acid? [Hint: you can find this as a physical property on Sigma.] C. Explain what a reflux is. D. Why can’t you separate (+) and (-) phenylsuccinic acid using a simple recrystallization? E. After the two enantiomers are separated, how can you check the purity of the final solid (how can you determine if it is pure (+)-phenylsuccinic acid)?

- Briefly explain the electronic effect of the substituent present in p-methoxybenzoic acid as compared to benzoic acid.In this experiment, we produce 2 different white solid compounds. We assume that one recovered white solid compound is p-toluic acid and we assume the other is p-tert butyl phenol based on their acid-base properties. Explain how we could be be more certain about the assignments (alternatively, if you don’t label your flasks/solids well, how could you determine what the structure of each of the isolated solid is) Hint: there are techniques from previous experiments that we could use to help identify the solids.The reactions given in the synthesis scheme showing the synthesis of D, a phremone of the moth.write the explicit structures of programs A,B,C and D.
