Vedclass · Answer

(A) The Etard reaction is a chemical reaction in which an aromatic or heterocyclic bound methyl group is directly oxidized to an aldehyde using chromyl chloride $(CrO_2Cl_2)$. The reaction involves the formation of a brown chromium complex intermediate,which upon hydrolysis yields the corresponding aldehyde. The correct representation is: $C_6H_5CH_3 + 2CrO_2Cl_2$ $\rightarrow C_6H_5CH(OCrOHCl_2)_2$ $\xrightarrow{H_3O^{+}} C_6H_5CHO$.

Which of the following represents the Etard reaction?
