Both aldehydes and ketones contain carbonyl group (>C = O) and are commonly known as carbonyl compounds. Identification of aldehydes and ketones is done by two important reactions of carbonyl group i.e. (i) addition reaction on double bond of >C = O group and (ii) oxidation of carbonyl group. Addition reactions of derivatives of ammonia are ...

361 Aldehydes, Ketones and Carboxylic Acids The carbonyl carbon atom is sp2-hybridised and forms three sigma (σ) bonds. The fourth valence electron of carbon remains in its p-orbital and forms a π-bond with oxygen by overlap with p-orbital of an oxygen. In addition, the oxygen atom also has two non bonding electron pairs.

The final product from aliphatic aldehydes or ketones contains both a carbonyl and an alcohol group. The product is called an aldol.
