Select the reagents that reduce nitriles to primary amines. Choose the correct answer from the options given below.

  1. A, B and C only
  2. A, D and E only
  3. A, C and D only
  4. B, D and E only

Answer

(3) A, C and D only

Solution

As per NCERT, nitriles on reduction with lithium aluminium hydride (LiAlH4) or catalytic hydrogenation produce primary amines:

R-C N H2/Ni R-CH2-NH2

A. (i) LiAlH4; (ii) H2O ⇒ R–CH2NH2 (reduces)

B. Sn + HCl is used to reduce nitro compounds to amines, not nitriles (does not reduce)

C. H2/Ni (catalytic hydrogenation) ⇒ R–CH2NH2 (reduces)

D. Na(Hg)/C2H5OH (Mendius reduction) ⇒ R–CH2NH2 (reduces)

E. Br2/aq. NaOH is the Hofmann bromamide reagent (amide → amine), not a reducing agent for nitriles (does not reduce)

∴ A, C and D only

Answer: (3)
