Q. Cannizaro reaction is given by
A) $HCHO$
B) [image:12_image375.emf]
C) [image:12_image376.emf]
D) $CH_{3}CH_{2}OH$
Explanation
(a)
Aldehyde, having no $\alpha -$hydrogen atom, undergoes Cannizaro reaction in which two molecules of the aldehyde are involved, one molecule being converted into the corresponding alcohol, and the other into the acid. The usual reagent for the Cannizaro reaction is aqueous or ethanolic alkali
$2HCHO + NaOH \rightarrow HCOONa + CH_{3}OH$
