Question

2c.) Correlate your structure with the 'H NMR spectrum by numbering the 'H NMR peaks (1.2,3, etc) starting with the most downfield peak and then label the structure accordingly. If you don't have a final structure, label the pieces and indicate what information you obtained from the spectra. (2 pts) 6 H J=705Hz 7 2 212 2 H J 7.2 Hz J=105 Hz 11 10 9 ppm 2d.) Correlate your structure with the 'C NMR spectrum by labeling the C NMR peaks (a.b,c, etc) starting with the most downfield peak and then label the structure accordingly. If you don't have a tinal structure, label the pieces and indicate what information you obtained from the spectra. pt) 200 18O 160 140 120 100 0 60 40 0 0

Explanation / Answer

CH3CH2COOCH(CH3)2

Common name isopropyl propanoate

Ester function is present by a peak at 180 ppm (approximate)

Carbonyl function can be identified by a peak at 2.1 ppm

Alkyl chains can be identified by splitting pattern. Isopropyl group can be identified by splitting pattern. Oxygen attached alkyl group can be identified by a peak at 70 ppm (approximate). All these values support the structure strongly as the written.
