butanal CHCHCHCHO butanone CHCOCHCH

Aldehydes and ketones contain the carbonyl group,
C=O. In aldehydes the carbonyl group is joined to
just one other carbon atom; in ketones the carbonyl
group is joined to two other carbon atoms.

The systematic names of aldehydes are derived
from the…

Aldehydes are readily oxidsed under mild conditions
to carboxylic acids. Ketones are not oxidised under
mild conditions.
The polar nature of the carbonyl group in aldehydes
and ketones enables them to undergo nucleophilic
addition of hydrogen cyanide to form
