Ketone

Physical properties

A carbonyl group is polar. This makes ketones polar compounds. The carbonyl groups interact with water by hydrogen bonding. It is a hydrogen bond acceptor, but not a hydrogen bond donator, and can not hydrogen bond to itself. This makes ketones more volatile than alcohols or carboxylic acids of similar molecular weight

Spectroscopic properties

Spectroscopy is an important means for identifying ketones. Ketones and aldehydes will display a significant peak in infrared spectroscopy, at around 1700 wavenumbers (slightly higher or lower, depending on the chemical environment)
