Chapter 6/7 - Aldehydes and Ketones Flashcards
(10 cards)
Aldehydes
Terminal functional groups containing a carbonyl bonded to at least 1 hydrogen
- Suffix -al; prefix oxo-
- In rings, suffix -carbaldehyde
Ketones
Internal functional groups containing a carbonyl bonded to 2 alkyl chains
- Suffix -one; prefix oxo- or keto-
α - carbon
Carbon adjacent to the carbonyl carbon
α-hydrogens
Hydrogens attached to the α-carbon
- Relatively acidic
Enolates
organic anions derived from the deprotonation of carbonyl (RR’C=O) compounds
Tautomers
Isomers that can be interconverted by moving a hydrogen and a double bond
Kinetic enolate
Favored by fast, irreversible reactions at lower temperatures with strong, sterically hindered bases
Thermodynamic enolate
Favored by slower, reversible reactions at higher temperatures with weaker, smaller bases
Enamines
tautomer of imines
Aldol
Contains both aldehyde and alcohol functional groups
