CBSE - XII Science - Chemistry - Aldehydes, Ketones and Carboxylic Acids
- Reagents : commonly a base such as NaOH or KOH is added to the aldehyde.
- The reaction involves an enolate reacting with another molecule of the aldehyde.
- Remember enolates are good nucleophiles and carbonyl C are electrophiles.
- The products of these reactions are b-hydroxyaldehydes or aldehyde-alcohols = aldols.
- The simplest aldol reaction is the condensation of ethanal. This is shown below in 2 different representations
- It may occur via these two mecanisms
