Log-In or Apply for Benefits | Colorado PEAK The peak at 66.75 ppm indicates there is a peak for carbon(s) in a carbon-oxygen single bond. The peak at 15.55 ppm indicates that there is a peak for carbon(s) in a carbon-carbon single bond. That would be consistent with C-C-O in the structure. It is not an alcohol (you are told that in the question), and the molecular formula is C 4 H 10 O ... The peak fitting challenges mentioned above make it difficult to accurately quantify the oxygen chemical states. In the copper (II) carbonate dihydroxide example shown above, the quantification of the carbonate versus hydroxide changes significantly according to peak fitting procedure.

In general, C-O stretching peaks are intense and normally fall between 1300 and 1000 cm-1 (going forward assume all peak positions are in cm-1 units). Because this wavenumber range is in the fingerprint region (2) there are often many peaks present between 1300 and 1000, but again the distinguishing feature of C-O stretches will be their intensity.

If a compound is suspected to be an aldehyde, a peak always appears around 2720 cm-1 which often appears as a shoulder-type peak just to the right of the alkyl C–H stretches. H–C=O stretch 2830-2695 cm-1; C=O stretch: aliphatic aldehydes 1740-1720 cm-1; alpha, beta-unsaturated aldehydes 1710-1685 cm-1; Figure 9. shows the spectrum of ...Colorado PEAK is the place to apply for and manage your medical, food, cash or other State of Colorado benefits online.
