What is the difference between aldol condensation and cannizzaro reaction

Related Answer. Aldol condensation takes place between :. Explain the difference between the respiration processes that take place in the presence and absence Aldol condensation will not take place in :.

Aldol condensation takes place in:. Aldol condensation takes place in. Aldol condensation will not take place in. The reaction requires a strong base as the catalyst. In this redox reaction, a hydride transfers from one substrate to another. There, one aldehyde molecule undergoes oxidation, yielding an acid, while the other aldehyde molecule undergoes reduction, forming an alcohol. However, this reaction sometimes produces unwanted byproducts. Figure An Example for Cannizzaro Reaction. Aldol condensation is an organic chemical reaction in which an enol or enolate ion reacts with a carbonyl compound giving a conjugated enone while Cannizzaro reaction is an organic redox reaction in which disproportionation of aldehydes give carboxylic acids and alcohols.

The key difference between aldol condensation and Cannizzaro reaction is that the former is a coupling reaction, whereas the later is a redox reaction. Aldol condensation is useful in the synthesis of organic compounds because it easily forms C-C bonds while Cannizzaro reaction is important because we can obtain both an alcohol and a carboxylic acid using the same reaction.

Overall, aldol condensation and Cannizzaro reaction are important organic synthesis reactions. What is Cannizzaro Reaction 4. Therefore, we can categorize it as a coupling reaction. The reaction is followed by a dehydration reaction, which gives a conjugated enone. The general reaction is as follows;. There are two steps: aldol reaction and dehydration reaction. Sometimes, there is a dicarboxylic reaction, as well. The dehydration of the aldol product can occur in two ways: strong base-catalyzed mechanism or acid-catalyzed mechanism.

The mechanism of aldol reaction that is catalyzed by a base is as follows:. Aldol condensation process is very important in organic synthesis processes. It is because this reaction is a good way to form a carbon-carbon bond. Cannizzaro reaction is an organic redox reaction in which a disproportionation of two molecules occurs to give a primary alcohol and a carboxylic acid.
