CARBONYL COMPOUNDS

• L.O.
• Identify and name ketones and aldehydes

CARBONYL COMPOUNDS - STRUCTURE
Structure carbonyl groups consists of a
carbon-oxygen double bond the bond is polar
due to the difference in electronegativity Di
fference ALDEHYDES - at least one H attached to
the carbonyl group

4
or RCHO
Aldehydes are named using the suffix al.
or HCHO is methanal
Or C6H5CHO. Benzenecarbaldehyde
5
Name this Aldehydes
Ethanal
Propanal
2-Methylpropanal
6
Ketones are named using the suffix one.
Propanone (acetone)
7
Name the following ketones
Butanone
3-Pentanone
3-Hexanone
2-methyl-3-hexanone
8
Solubility in water Shorter chain aldehydes and
ketones mix completely with water because of
hydrogen bonds between the oxygen of the carbonyl
group and water. As the length of the carbon
increases, they become less soluble in water.
