Vedclass · Answer

(D) The starting material contains an ester group $(EtO_2C-)$,a carboxylic acid group $(-COOH)$,and a nitrile group $(-CN)$.$1$. Treatment with $B_2H_6$ selectively reduces the carboxylic acid group to a primary alcohol $(-CH_2OH)$ without affecting the ester or nitrile groups.$2$. Treatment with $SnCl_2/HCl$ (Stephen reduction) reduces the nitrile group to an aldehyde $(-CHO)$ group.$3$. Finally,acidic hydrolysis $(H_3O^{+})$ hydrolyzes the ester group to a carboxylic acid group $(-COOH)$.Thus,the correct sequence of reagents is $(i) B_2H_6, (ii) SnCl_2/HCl, (iii) H_3O^{+}$.

The reagent$(s)$ required for the following conversion are:
