NAME ____________________________ Section _________ S’2019 CHE 211L Organic Chemistry II Laboratory Problem Set You can work in groups, but each student enrolled in CHE211L must turn in a completed problem set which is equivalent to a 50 point lab report. For problems 1 – 4, you are given a molecular formula, 1 H NMR absorption peaks, and characteristic IR absorptions for an unknown compound. In each case, propose a structure or in #4 two structures that are consistent with each set of data. 1. C 6 H 14 O 1 H NMR spectrum IR spectrum triplet, δ 0.8 (6H) strong peak 3600-3200 cm -1 singlet, δ 1.0 (3H) quartet δ 1.5 (4H) singlet, δ 1.6 (1H) 2. C 3 H 6 O 1 H NMR spectrum IR spectrum triplet, δ 1.11 (3H) a peak at 1730 cm -1 multiplet δ 2.46 (2H) triplet, δ 9.79 (1H) 3. C 4 H 8 O 3 1 H NMR spectrum IR Spectum triplet, δ 1.27 (3H) a broad peak in quartet, δ 3.66 (2H) 2500 – 3000 cm -1 region singlet, δ 4.13 (2H) and a peak at 1715 cm -1 singlet, δ 10.95 (1H) 4. C 9 H 10 O 1 H NMR spectrum IR spectrum Isomer A singlet, δ 2.15 (3H) peak at 1742 cm -1 singlet, δ 3.79 (2H) bd singlet,, δ 7.20 (5H) Isomer B triplet δ 1.22 (3H) IR spectrum

    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.
