Question

Five isomeric compounds with the molecular formula C5H10O were analyzed by IR spectroscopy. The fingerprint regions and the C-H stretch regions WERE NOT analyzed. Match each set of IR spectral data to the structure which is consistent with the data. (See attached image)

Only one structure for each IR data set. Not all structures will be used and no structure will be used more than one-time.

IR Spectra 1: A strong peak at 1710 cm1 IR Spectra 2: A strong, broad peak at 3430 cm1 but no peak at 1650 1670 cm1 IR Spectra 3: A strong, broad peak at 3420 cm and a peak at 1600 cm1 IR Spectra 4: A peak at 1660 cm1 but no peak at 3300 3600 cm IR Spectra 5: No peaks at 3330- 3600, 1650 1670, nor 1700 1750 cm Possible Structures (only one structure per each IR spectra) OH OH

Explanation / Answer

SOLUTION:

SPECTRA POSSIBLE STRUCTURS IR SPECTRA 1 B, Carbonyl group in Carboxylic acids give peak at 1710 cm-1 IR SPECTRA 2 D IR SPECTRA 3 G, OH 3400cm-1, C=C 1600cm-1 IR SPECTRA 4 C, IR SPECTRA 5 J
