Experiment VI: S N 1 Reaction: The syntesis of Triphenylmethyl methyl ether via the Triphenylmethyl Carbocation In this reaction, you will utilize the triphenylmethanol prepared in Experiment V to synthesize triphenylmethyl methyl ether via an S N 1 rection. You will have the opportunity to generate and “observe” the triphenylmethyl carbocation. Ph 3 -C-OH + 2 H 2 SO 4 Ph 3 -C + + H 3 O + + 2 HSO 4 - Ph 3 -C + + CH 3 OH Ph 3 -C-OCH 3 + H + PERFORM THIS REACTION IN THE HOOD Scale this reaction as necessary based on the amount of triphenylmethanol you obtained from Experiment V. Before starting the reaction, set aside a few milligrams of triphenylmethanol for running a comparison TLC after you have isolated the product (starting material (SM)-vs-product): In a 25 mL Erlrnmeyer flask, add 1.0 g triphenylmethanol and grind the crystals to a fine powder using a glass rod. Carefully add 10 mL of con. H 2 SO 4 and stir the mixture with the glass rod to effect complete dissolution. You should observe a red-brown to light yellow solution. The color is due to the presence of the carbocation.

    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.
