Definition
| contains the carbon oxygen double bond |

|
Term
|
Definition
| interconverting between isomers by moving a hydrogen and a double bond; keto and enol are tautomers of each other |
|
|
Term
|
Definition
| deprotonated enol; good nucleophile |
|
|
Term
|
Definition
when an enolate attacks an α,β-unsaturated carbonyl, creating a bond

|
Term
| kinetic and thermodynamic enolates |
|
Definition
| the kinetic enolate will form with the less substituted carbon and the thermodynamic enolate will form with the more substituted carbon; same properties for kinetic and thermodynamic products still apply |

Term
|
Definition
tautomers of each other; the nitrogen double bonded to the carbon in the imine is converted to a double bond between two carbons

Definition
- the aldehyde or ketone acts as both nucelophile and electrophile resulting in the formation of a carbon-carbon bonds in a new molecule called an aldol (contains both aldehyde and alcohol functional groups)
- the nucleophile is the enolate formed from the deprotonation of the α-carbon
- the electrophile is the aldehyde or ketone in the form of the keto tautomer
- First, a condensation reaction occurs in which the two molecules come together
- After the aldol is formed, a dehydration reaction occurs resulting in an α,β-unsaturated carbonyl
