Vedclass · Answer

(D) Rosenmund reduction involves the catalytic hydrogenation of an acid chloride to an aldehyde using $H_2$ gas in the presence of $Pd/BaSO_4$. To prepare formaldehyde $(HCHO)$,the required starting material would be formyl chloride $(HCOCl)$. However,formyl chloride is highly unstable at room temperature and spontaneously decomposes into carbon monoxide $(CO)$ and hydrogen chloride $(HCl)$. Therefore,$HCHO$ cannot be prepared by the Rosenmund reduction method.
