Where do aldehydes show up on IR?
IR Spectra
This is a saturated ketone, and the C=O. band appears at 1715.
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.What is the infrared of aldehyde?
Infrared Spectroscopy
In addition, aldehydes show two characteristic C–H absorptions between 2700–2760 and 2800–2860 cm' In addition, aldehydes show two characteristic C–H absorptions between 2700–2760 and 2800–2860 cm'–1.
These absorbances are important for distinguishing between aldehydes and ketones.Aldehydes and ketones show a strong C═O C═O bond absorption in the IR region from 1660 to 1770 cm–1, as the spectra of benzaldehyde and cyclohexanone demonstrate (Figure 19.15).
In addition, aldehydes show two characteristic C–H absorptions between 2700–2760 and 2800–2860 cm–1.20 sept. 2023
