Question

The reagent(s) used for the reduction of aldehydes and ketone into alcohols is/are (A) finely divided metals such as Pt / Pd / Ni (B) sodium borohydride (C) lithium aluminium hydride (D) All of the above

Tardigrade Admin · Accepted Answer

Aldehydes and ketones are reduced to the corresponding alcohols by the addition of hydrogen in the presence of catalysts (catalytic hydrogenation). The usual catalyst is finely divided metal such as platinum, palladium or nickel.
Alcohols are also prepared by treating aldehydes and ketones with sodium borohydride

(N a B H_{4})

or lithium aluminium hydride
