WebJul 31, 2024 · A carbonyl group in a compound can be positively identified by the strong infrared absorption band in the region 1650 - 1850 cm − 1, which corresponds to the stretching vibration of the carbon-oxygen double bond. The position of the band within this frequency range depends on the molecular environment of the carbonyl group. WebAs a result, the carbonyl group is best described as a hybrid of the following resonance structures. We can represent the polar nature of this hybrid by indicating the presence of a slight negative charge on the oxygen ( d -) and a slight positive charge ( d +) on the carbon of the C=O double bond.
