Question

A proton and Carbon-13 NMR for an unknown is described. First, the proton NMR spectrum. There is a multiplet at 1.849,1.838,1.834,1.824,1.820,1.809 with an integrated value of 0.945. There is a triplet at 1.696,1.691,1.677 with an integrated value of 1.383. There is a triplet at 1.031,1.017,1.022 with an integrated value of 0.898. There is a triplet at 0.923,0.908,0.894 with an integrated value of 1.013. The transmitter frequency is 500.133001 MHz. Second, the Carbon-13 NMR spectrum. There is a triplet at 77.252, 76.998, 76.744. There is a singlet at 62.287. There is a singlet at 51.522. There is a singlet at 43.243. There is a singlet at 31.780. There is a singlet at 26.429. There is a singlet at 20.962. There is a singlet at 13.366. There is a singlet at 12.069. The transmitter frequency is 125.774803 MHz.

Describe the proton NMR and Carbon-13 NMR using the American Chemical Society (ACS) format for the experimental data.

Explanation / Answer

1H NMR (500 MHZ, CDCl3) 1.84 – 1.80 (m, 1 H), 1.69 (t, 1H), 1.01 (t, 1H), 0.90 (t, 1H).

13C NMR (125 MHZ, CDCl3) 62.28, 51.52, 43.24, 31.78, 26.42, 20.96, 13.36, 12.06.

77.252, 76.998, 76.744 these peaks corresponds to CDCl3
