E-4 Na acut e Skin irritati on toluene 92.1 4 0.87 110 -93 ~ 10 mL 4.6 E-4 na Acut e flamm able Calculations: 1. Calculate the number of moles of 1-bromododecane, and N,N,N’,N’- tetramethylethylenediamine used in part I. What is the limiting reagent? 1.4E-4 moles 1-b x 1 / 2 = 7.0 E-5 2.9E-5 moles N x 1/ 1 = 2.9E-5 2. Calculate the theoretical yield of 12-2-12. [Note that you should include the two bromides (Br - ) in your calculation of the molecular mass.] 7.0E-5 x 1015.4/1 = 7.1E-2 Flow chart Part I: A. Combine 1.0 mL acetone, 3.1 mL 1-bromododecane ), and 0.65 mL N,N,N’,N’- tetramethylethylenediamine in 25 mL Erlenmeyer flask mix reagents let flask sit 1 week at room temp add acetone after week is up use vacuum filtration to separate solid weigh, determine MP and calculate % yield of solid B.

    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.
