Question
Identify the unknown compound using the C NMR and H NMR spectra
Spectroscopy Unknown. The spectra and data provided were obtained from a pure organic molecule. For ¹H NMR Spectra, the integral is given in number of hydrogens (#H) or as a relative ratio. Important coupling constants (J-values) are listed next to the peaks for some examples. For some spectra, an inset (grey box) is also given showing a "zoom-in" on an important part of the spectrum. Mass Spectrum (not shown): [M] = 222 (100%) m/z IR Spectrum (not shown): 3098, 2981, 1745, 1720, 1600, 1490 cm¹ (all listed are strong (s) unless otherwise indicated) ¹H NMR Spectrum (400 MHz, CDCI3, 25 °C) 9 d (J= 8 Hz) 180 --00 2H d (J= 8 Hz) 2H (C) (C) (C) 160 (CH) 6 140 q 120 PPM 2H 1³C NMR Spectrum, proton-decoupled (125 MHz, CDCl3, 25 °C) (CH) (C) -11- 100 PPM 3 80 q 2H 60 (CH₂) -2 m 40 6H (CH₂) (CH3) (CH3) 20
