Question

Mendius reaction involves the

• A. reduction of aldehydes to give alcohols
• B. reduction of nitriles with sodium and ethanoli
• C. oxidation of nitrile
• D. hydrolysis of cyanides

Answer 1

Answer: (B)

reduction of nitriles with sodium and ethanoli

Answer 2

Mendius reaction. The reduction of cyanides to 1$^{\circ}$ amines by using ethanolic sodium is called as Mendius reaction. {R-C \equiv N + 4[H]->C[Na/alc]\underset{\mathrm{1^\circ , amine}}{ {R-CH_2-NH_2}}}
