[PDF] aldehyde functional group ir spectrum

IR SPECTRUM OF ALDEHYDES AND KETONES Aldehydes and ketones show a strong, prominent, stake-shaped band around 1710 - 1720 cm-1 (right in the middle of the spectrum). This band is due to the highly polar C=O. bond. Because of its position, shape, and size, it is hard to miss.

  • What is the IR spectrum of an aldehyde group?

    IR Spectra
    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 functional group region of the IR spectrum?

    In general terms it is convienient to split an IR spectrum into two approximate regions: 4000-1000 cm-1 known as the functional group region, and. < 1000 cm-1 known as the fingerprint region.
