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 $(-OH)$.$1$. $Zn-Hg / HCl$ (Clemmensen reduction) is an acidic condition and would cause the dehydration of the alcohol group.$2$. $H_2N-NH_2, KOH / 	ext{ethylene glycol}$ (Wolff-Kishner reduction) provides a basic condition, which is compatible with the presence of an alcohol group.$3$. Therefore, the appropriate reagent is $H_2N-NH_2, KOH / 	ext{ethylene glycol}$.

The appropriate reagent for the following transformation is:
(Reactant: $3-$hydroxycyclopentyl methyl ketone; Product: $3-$hydroxycyclopentyl ethyl group)
