PLEASE IDENTIFY THE UNKNOWN COMPOUND ALONG WITH ITS STRUCTURE. PLEASE EXPLAIN AND ANALYZE EACH SPECTRUM.
Homework Answers
1H-NMR
One peak is present around 9.7 ppm, 1H. it is the range of C-H of aldehyde which clearly indicates that the presence of an aldehydic group.
The peak at 2.4 ppm, 2H indicates it is CH2 which is connected to carbonyl group
Other peaks 1.58 ppm, 2H indicates the presence of CH2 and 1.28 ppm, 4H means the presence of 2 CH2 groups
Finally, peak at 0.88 ppm, 3H indicates the presence of CH3
IR
1724 cm-1 stretching of C=O indicates carbonyl is present
2730 and 2840 cm-1 peaks C-H stretching of CHO clearly tells us presence of aldehyde functional group
2900 to 300cm-1 peaks Sp3 C-H (alkyl group)
13 C NMR
Total 6 peaks are present means 6 types of Carbons are present in the molecule.
Peak at 202 ppm is from C of aldehyde.
Peak at 43 ppm is peak of CH2 which is connected to CHO
31, 27, 22 ppm peaks are from 3 CH2 groups.
14 ppm peak is from CH3 group.
If you connect all the analysis . The compound will be hexanal.
