What is the Difference Between Aldol Condensation and Cannizzaro Reaction?
🆚 Go to Comparative Table 🆚The main difference between Aldol Condensation and Cannizzaro's Reaction lies in the type of reaction and the presence of α-hydrogens:
- Aldol Condensation:
- It is an organic chemical reaction.
- Occurs in the presence of α-hydrogens.
- The reaction involves an enol or enolate combining with a carbonyl compound to form either β-hydroxyaldehyde or β-hydroxyketone.
- It is a coupling reaction, as two compounds couple to form one large compound.
- Cannizzaro's Reaction:
- It is an organic redox reaction.
- Occurs in the absence of α-hydrogens.
- The reaction involves the disproportionation of two non-enolizable aldehydes, forming a primary alcohol and a carboxylic acid.
In summary, Aldol Condensation is a type of organic chemical reaction involving enols or enolates and carbonyl compounds, while Cannizzaro's Reaction is an organic redox reaction involving the disproportionation of non-enolizable aldehydes.
Comparative Table: Aldol Condensation vs Cannizzaro Reaction
The main difference between aldol condensation and Cannizzaro reaction is that aldol condensation is a coupling reaction, whereas the Cannizzaro reaction is a type of organic redox reaction. Here is a comparison table highlighting the key differences between the two reactions:
Feature | Aldol Condensation | Cannizzaro Reaction |
---|---|---|
Type of Reaction | Coupling reaction | Redox reaction |
Reactants | Enol or enolate and a carbonyl compound | Two non-enolizable aldehydes |
Products | β-hydroxyaldehyde or β-hydroxyketone | Primary alcohol and a carboxylic acid |
In an aldol condensation reaction, an enol or an enolate combines with a carbonyl compound to form either β-hydroxyaldehyde or β-hydroxyketone. On the other hand, in a Cannizzaro reaction, one aldehyde molecule undergoes oxidation to form a carboxylic acid, while another aldehyde molecule undergoes reduction to form a primary alcohol.
