How would you use IR and 1H-NMR spectroscopy to distinguish between these two isomeric compounds? For IR, consider the absorption of the carbonyl group. For 1H-NMR, consider the number of signals observed. Select the IR frequency and number of NMR signals that is diagnostic for either isomer a or isomer b. Isomer A: N-methylbutanamide Isomer B: N,N-dimethylpropanamide IR: _______ cm-1 a-1680 a-1690 a-1735 a-1810 a-2250 b-1650 b-1690 b-1710 b-2250 1H-NMR: _____ signals a-4 a-5 b-3 b-4 b-5 b-6
