Vedclass · Answer

(C) The Etard reaction $(I)$ involves the oxidation of toluene to benzaldehyde using chromyl chloride $(CrO_2Cl_2)$ in the presence of $CCl_4$ as a solvent. The reaction proceeds through the formation of a brown chromium complex,which is subsequently hydrolyzed to give benzaldehyde.The Stephen reaction $(II)$ involves the reduction of nitriles $(R-CN)$ to imines using stannous chloride $(SnCl_2)$ in the presence of hydrochloric acid $(HCl)$,followed by hydrolysis to yield the corresponding aldehyde $(R-CHO)$.

The reagents used in the Etard reaction $(I)$ and the Stephen reaction $(II)$ are:
