Vedclass · Accepted Answer

$NH_2NH_2, OH^-$

Vedclass · Answer

(B) The given transformation involves the reduction of a ketone group $(C=O)$ to a methylene group $(-CH_2-)$ while keeping the hydroxyl $(-OH)$ group intact.$1.$ $Zn(Hg)/HCl$ is the reagent for Clemmensen reduction,which is acidic in nature. It would likely cause the dehydration of the alcohol group.$2.$ $NH_2NH_2, OH^-$ is the reagent for Wolff-Kishner reduction,which is basic in nature. It reduces the carbonyl group to a methylene group without affecting the hydroxyl group.$3.$ $H_2/Ni$ would reduce the ketone to an alcohol.$4.$ $NaBH_4$ would reduce the ketone to an alcohol.Therefore,the correct reagent is $NH_2NH_2, OH^-$.
