In the warehouse of the company Tumany Amines, Inc., three unidentified compounds have been found. The president of the company, Wotta Stench, has hired you to identify them from their spectra. (a) Compound A (C9H13NO): IR spectrum: 3360, 3280 cm1 (doublet); 1611 cm1 ; no carbonyl absorption. NMR spectrum shown in Fig. P23.71a. (b) Compound B (C6H16N2): IR spectrum: 3281 cm1 . NMR spectrum: d 1.1 (8H, t, J 5 7 Hz), d 2.66 (4H, q, J 5 7 Hz), d 2.83 (4H, s). (Hint: The triplet at d 1.1 conceals another broad resonance that contributes to the integral.) (c) Compound C (C6H13N): IR spectrum: 3280, 1653, 898 cm1 . NMR spectrum in Fig. 23.71b
