What is the product of reduction of Nitriles with Lithium Aluminium Hydride?

Amines

The correct answer is Option (3) → Amines

• Nitriles (R–C≡N) can be reduced by LiAlH₄, a strong reducing agent:

$R–C≡N \overset{\text{LiAlH}_4}{\longrightarrow} R–CH_2–NH_2$

• The triple bond between carbon and nitrogen is reduced to a single bond, forming a primary amine.

 Hence, the product of reduction of nitriles with LiAlH₄ is amines.
