Competing Nucleophiles Procedure Notes The procedure in the lab text only makes enough nucleophilic medium for one alcohol in 21A and t- butanol in 21B therefore each person will be assigned one alcohol from 21A and t-butanol for 21B. In order to get enough product, we will triple ALL amounts for this experiment including the nucleophilic medium. We will also use our 125 mL separatory funnel everywhere the procedure calls for a centrifuge tube. The procedure on this page represents all amounts listed in the lab text after tripling . Nucleophilic Medium Combine all the reactants as prescribed but remember to triple all amounts listed in the lab text. (i.e. 30g ice, 22.8mL H2SO4, 5.7g NH4Cl, and 10.8g NH4Br). Place the ice in a beaker then add the acid. Once the ice is melted, pour the solution into a 250 mL Erlenmeyer flask. Weigh the solids using tared weigh boats. The salts can be crushed to powder, in the weigh boats, using your scoopula handle. Transfer the salts in the two weigh boats to the Erlenmeyer flask. It is necessary

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
