Vedclass · Answer

(B) The transformation involves the reduction of a ketone group $(-C=O)$ to a methylene group $(-CH_2-)$ in the presence of an alcohol group $(-OH)$.$Zn-Hg / HCl$ (Clemmensen reduction) is acidic and would cause the dehydration of the alcohol group.$H_2N-NH_2, KOH / 	ext{ethylene glycol}$ (Wolff-Kishner reduction) is a basic condition,which is compatible with the presence of an alcohol group.Therefore,the appropriate reagent is $H_2N-NH_2, KOH / 	ext{ethylene glycol}$.
