Tell precisely how you would use the proton NMR spectra to distinguish between the following pairs of compounds: propanol and propanone
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

(a) Explain how you would distinguish the three isomers below using NMR spectroscopy. Give specific examples of peaks, chemical shifts and splitting patterns that would illustrate the differences (b) Determine the structure of C8H14O from the NMR data below. (c) Draw the 1H-NMR spectrum you would expect for the following compounds. Show clearly the splitting pattern and the integration values.
113 pts) consider the molecules shown below. Briefly explain how you could use IR spectroscopy to distinguish between each pair of compounds. Give approximate frequencies for any diagnostic peaks you would expect (or not expect) to observe. Focus on the key signal(s) that would allow you to tell the two apart.
please answer #5
5. Which type of spectroscopy (IR, 'H NMR, and/or "C NMR) would be good to distinguish between propanal and propanoic acid? State what you would observe for each compound in each type of spectroscopy and whether that type of spectroscopy would be a good way to distinguish between the two compounds.
