Sniffing out carbonyl compounds

Carbonyl compounds (aldehydes and ketones) are found in some surprising places and we often get a whiff of them without realising. How can we detect them using spectroscopy?

The terms in bold link to topics in the AQA, Edexcel, OCR, WJEC, CCEA and SQA exam specifications.

Aldehydes and ketones contain the carbonyl group. Tests to distinguish between them depend on aldehydes being easily oxidised to carboxylic acids. Aldehydes and ketones can also be recognised by their infrared, 1H and 13CNMR spectra. Aldehydes and ketones undergo nucleophilic addition reactions. Some of these are followed by elimination of a water molecule in a condensation reaction. This article also touches on E/Z isomerism.
