Vedclass · Answer

(D) The given reaction is the reduction of a ketone to an alkane (specifically,a methylene group). $1$. $Zn-Hg/HCl$ is the Clemmensen reduction,which reduces ketones to alkanes. $2$. $HI/Red \ P, \ \Delta$ is a strong reducing agent that reduces ketones to alkanes. $3$. $(i) \ NH_2-NH_2, \ (ii) \ OH^-/\Delta$ is the Wolff-Kishner reduction,which also reduces ketones to alkanes. $4$. $NaBH_4$ is a mild reducing agent that reduces aldehydes and ketones to alcohols,not to alkanes. Therefore,$NaBH_4$ cannot be used for this interconversion.

Which among the following reagents cannot be used for the above interconversion? The reaction involves the reduction of a ketone group $(>C=O)$ to a methylene group $(-CH_2-)$.
