chemical compound - Academic Dictionaries and …

In a ketone, both atoms bonded to the carbonyl carbon are other carbon atoms, and, in an aldehyde, at least one atom on the carbonyl carbon is a hydrogen. Similar to the double bond of alkenes, the carbon-oxygen double bond is made up of a σ bond, whose electron pair lies between the bonded atoms, and a π bond, whose electron pair occupies space on both sides of the σ bond.
