Aldehydes Ketones and Carboxylic Acids Report Error

intramolecular Cannizzaro reaction

crossed Cannizzaro reaction

intermolecular Cannizzaro reaction

Tischenko reaction

Solution:

Two molecules of the same aldehyde are reacting in presence of alkali to form sodium salt of the acid and an alcohol, hence it is an example of intermolecular Cannizzaro reaction.
