Study Notes
Carbonyl Compounds
- Aldehydes and ketones are associated with the carbonyl functional group, characterized by a carbon-oxygen double bond (C=O).
Aldehydes
- The general formula for aldehydes is RCHO, where R is a hydrogen atom or an alkyl group.
- Ethanal is an example of an aldehyde, and its common name is acetaldehyde.
Ketones
- A ketone is a compound that contains a carbonyl group bonded to two alkyl groups, such as butanone (CH₃COCH₂CH₂CH₃).
Carboxylic Acids
- Carboxylic acids contain the carboxyl functional group, which is characterized by a carbon-oxygen double bond and a hydroxyl group (COOH).
