Dimethyl acetaldehyde

Vedclass · Answer

(C) The reaction described is the $Cannizzaro$ reaction. Aldehydes that do not contain an $\alpha$-hydrogen atom undergo self-oxidation and reduction (disproportionation) when treated with concentrated alkali. $Benzaldehyde$ $(C_6H_5CHO)$ has no $\alpha$-hydrogen. $Trimethylacetaldehyde$ $((CH_3)_3CCHO)$ has no $\alpha$-hydrogen. $Formaldehyde$ $(HCHO)$ has no $\alpha$-hydrogen. $Dimethyl$ $acetaldehyde$ (isobutyraldehyde,$(CH_3)_2CHCHO$) contains one $\alpha$-hydrogen atom attached to the $\alpha$-carbon. Therefore,$Dimethyl$ $acetaldehyde$ does not undergo the $Cannizzaro$ reaction. The correct option is $C$.
