• # question_answer Clemmensens reduction of ketone is carried out in A)  ${{H}_{2}}$ with Pd catalyst B)  glycerol with $KOH$ C)  $LiAl{{H}_{4}}$ with water D)   $Zn-Hg$with $HCl$

Reduction of aldehydes and ketones to their corresponding hydrocarbons in the presence of $Zn-Hg$ with cone $HCl$ is known as Clemmensens reduction, eg,$\underset{acetaldehyde}{\mathop{C{{H}_{3}}CHO}}\,+4[H]\xrightarrow[conc.\,HCl]{Zn/Hg}\underset{etthane}{\mathop{C{{H}_{3}}C{{H}_{3}}}}\,+{{H}_{2}}O$
