The cannizzaro reaction is an example of a general class of reactions known as the disproportionation reactions. Explain how this term applies to the cannizzaro reaction
Homework Answers
By definition disproportionation reaction is the type of reaction where an element simultaneously gets oxidised and reduced. In Cannizaro reaction any aldehyde which is not having alpha hydrogen atom when reacts with strong alkali produces an acid (oxidized product) and an alcohol (reduced product). For example when PhCHO treated with NaOH produces PhCH2OH and PhCOOH.
So, the oxidation and reduction (redox) is taking place for the same compound which is by analogy is a disproportionation reaction.

For this question, you can ignore part (5). (10 points each) 3.11. The Cannizzaro reaction is a disproportionation that takes place in strongly basic solution and converts aromatic aldchydes to the corresponding benzyl alcohol and sodium benzoate. Several mechanisms, all of which involve a hydride transfer as a key step, have been postulated. On the basis of the following information, formulate one or more mechanisms that would be consistent with all the data provided. Indicate the significance of each observation...
