$D$

Vedclass · Answer

(D) Due to the presence of bulky aryl groups,the nucleophilic attack on the $sp^2$ carbon of the $>C=O$ group experiences steric hindrance,decreasing the reaction rate.$(B)$ Fehling's solution is a mild oxidizing agent and cannot oxidize benzaldehyde.$(C)$ Ethanal contains $\alpha$-hydrogens which are acidic due to the electron-withdrawing effect of the carbonyl group,allowing for enolization.$(D)$ The $-NO_2$ group at the $p$-position exerts a strong $-R$ (resonance) and $-I$ (inductive) effect,which increases the partial positive charge on the carbonyl carbon,making it more susceptible to nucleophilic attack. Thus,$p$-nitrobenzaldehyde is more reactive than benzaldehyde. Therefore,statement $D$ is incorrect.

List-$I$	List-$II$
$A$. Benzaldehyde	$i$. Phenolphthalein
$B$. Phthalic anhydride	$ii$. Benzoin condensation
$C$. Phenyl benzoate	$iii$. Oil of wintergreen
$D$. Methyl salicylate	$iv$. Fries rearrangement
