Advanced Organic Chemistry: Infrared spectrum of propanal

Interpreting the infrared spectrum of propanal (propionaldehyde)

Doc Brown's Chemistry Advanced Level Pre-University Chemistry Revision Study Notes for UK IB KS5 A/AS GCE advanced A level organic chemistry students US K12 grade 11 grade 12 organic chemistry courses involving molecular spectroscopy analysing infrared spectra of propanal

infrared spectrum of propanal wavenumbers cm-1 functional group detection fingerprint pattern identification of propionaldehyde doc brown's advanced organic chemistry revision notes 

Spectra obtained from a liquid film of propanal. The right-hand part of the of the infrared spectrum of propanal, wavenumbers ~1500 to 400 cm-1 is considered the fingerprint region for the identification of propanal and most organic compounds. It is due to a unique set of complex overlapping vibrations of the atoms of the molecule of propanal.

Interpretation of the infrared spectrum of propanal  (propionaldehyde)

The most prominent infrared absorption lines of propanal

The strongest and most characteristic absorption band of propanal is at wavenumbers ~1740 to 1720 cm-1 for the stretching vibrations of the carbonyl group bond C=O.

There are multiple C-H absorptions at wavenumbers ~1215 to 1435 cm-1 and ~3000 cm-1, but non particularly characteristic of aldehydes.

The absence of other specific functional group bands will show that particular functional group is absent from the propanal molecular structure.

Key words & phrases: propionaldehyde image and diagram explaining the infrared spectrum of propanal, complete infrared absorption spectrum of propanal, comparative spectra of propanal, prominent peaks/troughs for identifying functional groups in the infrared spectrum of propanal, important wavenumber values in cm-1 for peaks/troughs in the infrared spectrum of propanal, revision of infrared spectroscopy of propanal, fingerprint region analysis of propanal, how to identify propanal from its infrared spectrum, identifying organic compounds like propanal from their infrared spectrum, how to analyse the absorption bands in the infrared spectrum of propanal detection of aldehyde functional groups in the propanal molecule example of the infrared spectrum of a molecule like propanal with a functional group aldehyde propionaldehyde
