Vedclass · Answer

(C) Aldehydes that do not possess any $\alpha$-hydrogen atoms undergo the Cannizzaro reaction in the presence of a concentrated base. $(a)$ $HCHO$ (Formaldehyde): No $\alpha$-carbon,hence no $\alpha$-hydrogen. It undergoes Cannizzaro reaction. $(b)$ $C_6H_5-CHO$ (Benzaldehyde): The $\alpha$-carbon (the carbon attached to the aldehyde group) has no hydrogen atom attached to it. It undergoes Cannizzaro reaction. $(c)$ $CH_3-C(CH_3)_2-CHO$ ($2$,$2$-Dimethylpropanal): The $\alpha$-carbon is bonded to three methyl groups and has no $\alpha$-hydrogen. It undergoes Cannizzaro reaction. $(d)$ $Ph-CH_2-CHO$ (Phenylacetaldehyde): The $\alpha$-carbon is attached to two hydrogen atoms. It does not undergo Cannizzaro reaction. Therefore,compounds $(a)$,$(b)$,and $(c)$ undergo the Cannizzaro reaction.

Which of the following compounds undergo Cannizzaro reaction?
$(a)$ $HCHO$
$(b)$ $C_6H_5-CHO$
$(c)$ $CH_3-C(CH_3)_2-CHO$
$(d)$ $Ph-CH_2-CHO$
