Reduction of ketones cannot be carried outwith which of the following reagents ?

Step-by-step solution

Ketones are reduced to secondary alcohols by sodium borohydride ( ( N a BH ₄ ) ) or lithium aluminum hydride ( ( LiAl H ₄ ) ) as well as by catalytic hydrogenation. [ (R- i C _ 1 R ^ 1 )₄ A l⁻+4 H⁺(a q) R- 1 C -O H+A l³⁺(a q) ] Carbonyl carbon of ketones are reduced to ( - CH ₂- ) group in treatment with zinc amalgam and conc. ( HCl ( Clemmensen ) reduction) or with hydrazine followed by heating with sodium or ( KOH ) in high boiling solvent such as ethylene glycol (Wolff-Kishner reduction). Clemmensen reduction Wo
