Vedclass · Answer

(C) The Cannizzaro reaction is characteristic of aldehydes that lack $\alpha$-hydrogen atoms.$A$ (Benzaldehyde) lacks $\alpha$-hydrogens and undergoes the Cannizzaro reaction.$B$ (Trimethylacetaldehyde or Pivalaldehyde) lacks $\alpha$-hydrogens and undergoes the Cannizzaro reaction.$D$ (Formaldehyde) lacks $\alpha$-hydrogens and undergoes the Cannizzaro reaction.$C$ ($CCl_3CHO$,Chloral) lacks $\alpha$-hydrogens,but it does not undergo the typical Cannizzaro disproportionation reaction. Instead,in the presence of concentrated alkali,it undergoes a haloform-type cleavage reaction to produce chloroform $(CHCl_3)$ and a formate salt $(HCOO^-)$.

List-$I$	List-$II$
$A$. Tollen's reagent	$I$. Para-rosaniline + $SO_2$
$B$. Schiff's reagent	$II$. Rochelle salt + $aq. NaOH$
$C$. Rosenmund reduction	$III$. Ammoniacal silver nitrate
$D$. Fehling solution $B$	$IV$. $Pd + BaSO_4$

Which of the following will not give the Cannizzaro reaction?
