Vedclass · Answer

(D) The given reaction is the conversion of $4$-hydroxycyclohexanone to cyclohexanol. In this reaction,the carbonyl group $(C=O)$ is reduced to a methylene group $(-CH_2-)$,while the hydroxyl group $(-OH)$ remains unchanged. $LiAlH_4$ and $DIBALH$ are reducing agents that reduce carbonyl groups to alcohols,not methylene groups. $Zn-Hg/HCl$ is the reagent for Clemmensen reduction,which reduces carbonyl groups to methylene groups. However,it is acidic and would cause the dehydration of the alcohol or other side reactions. $NH_2-NH_2/OH^-$ is the reagent for Wolff-Kishner reduction,which is a basic medium reduction that converts carbonyl groups to methylene groups without affecting the hydroxyl group. Therefore,the correct reagent is $NH_2-NH_2/OH^-$.

Which of the following reagents must be used in the given interconversion? The reaction involves the reduction of $4$-hydroxycyclohexanone to cyclohexanol,where the carbonyl group is reduced to a methylene group while the hydroxyl group remains unaffected.
