Vedclass · Answer

(B) The given transformation involves the reduction of a ketone group $(C=O)$ to a methylene group $(-CH_2-)$ while keeping the carbon-carbon double bond $(C=C)$ and the hydroxyl group $(-OH)$ intact. $NaBH_4$ reduces ketones to alcohols but does not reduce the $C=O$ group to $CH_2$. $Zn-Hg / HCl$ (Clemmensen reduction) is acidic and would likely cause dehydration of the alcohol or other side reactions. $NH_2NH_2, \mathop{OH}\limits^\Theta$ (Wolff-Kishner reduction) is a basic condition that specifically reduces the carbonyl group of aldehydes and ketones to a methylene group without affecting the $C=C$ double bond or the alcohol group. Therefore,the correct reagent is $NH_2NH_2, \mathop{OH}\limits^\Theta$.
