This quiz is open textbook / open notes - but you must work alone. You cannot use the internet or the solutions manual for the book. Scan in your work and record an explanation of your mechanism. You may record this any way that you like. One way would be to start an individual Zoom meeting, start recording, "share your screen" and then talk through the problem. This will be converted to an .mp4 file that you can upload into Canvas using the "record/upload media" feature. Pyridine, benzoic acid and benzene are dissolved in ethyl acetate. Design and provide a plan / flow chart for separating and isolating each of these components. Pyridine and benzene are liquids at room temperature. Benzoic acid is a solid. You have ethyl acetate, 2M NaOH, 2M HCI and anhydrous MgSO4 available, as well as all the glassware and equipment that you used in the organic lab this year. Provide accurate acid/base reactions for any…arrow_forward
