Study Notes

Aldehydes and Ketones: Nomenclature

IUPAC Nomenclature

Aldehydes:
- Named as derivatives of the parent alkane
- Replace the terminal -e of the alkane with -al
- Example: methanal (formaldehyde), ethanal (acetaldehyde)
Ketones:
- Named as derivatives of the parent alkane
- Replace the terminal -e of the alkane with -one
- Example: propanone (acetone), butanone (ethyl methyl ketone)

Substitutive Nomenclature

Prefixes used to indicate the substituents:
- Alkyl groups: methyl-, ethyl-, propyl-, etc.
- Halogens: chloro-, bromo-, iodo-, etc.
- Other substituents: hydroxy-, amino-, etc.
Example: 3-chloropropanal, 2-methyl-1-phenylpropan-1-one

Functional Class Nomenclature

Aldehydes:
- Named as a derivative of the parent aldehyde
- Example: 2-methylbutanal, 3-phenylpropanal
Ketones:
- Named as a derivative of the parent ketone
- Example: 2-methylbutan-2-one, 3-phenylpropan-2-one
