Study Notes
Structure and Functional Groups
- Ketones have a carbonyl group (C=O) flanked by carbon atoms on both sides.
- The carbonyl carbon is bonded to two other carbon atoms, differentiating ketones from aldehydes.
Simplest Ketone
- Acetone, also known as propanone, is the simplest ketone with the chemical formula C3H6O.
Nomenclature
- In IUPAC nomenclature, ketone names are derived from the longest carbon chain that contains the carbonyl group, with the suffix “-one” indicating the presence of a ketone.
- For example, the name of a ketone with five carbon atoms is "pentan-2-one," indicating the position of the carbonyl group.
Traditional Names
- Traditional nonsystematic names of ketones often use common names based on their structure, such as “acetone” for propanone.
- These names may refer to specific groups linked to the carbon atoms adjacent to the carbonyl, especially in simpler ketones.
