Vedclass · Answer

(D) Let us analyze each reaction:$A$. Rosenmund reduction: Acid chloride is reduced to aldehyde using $H_2$ and $Pd/BaSO_4$. This is correct.$B$. Nitriles are reduced to aldehydes using $DIBAL-H$ followed by hydrolysis. This is correct.$C$. Esters are reduced to aldehydes using $DIBAL-H$ at low temperature followed by hydrolysis. This is correct.$D$. Oxidation of primary alcohols with strong oxidizing agents like $Na_2Cr_2O_7/H_2SO_4$ (Jones reagent) typically proceeds further to carboxylic acids. Therefore,$4$-methylbenzyl alcohol will be oxidized to $4$-methylbenzoic acid,not $4$-methylbenzaldehyde. Thus,this reaction does not represent the correct product.
