Question

The product P in this reaction is \[ R - \text{NC} - \text{LiAlH}_4 \quad \longrightarrow \quad P \]

• A. \( \text{R}-NH_2 \)
• B. \( \text{R}-N-CH_3 \)
• C. \( \text{R}-C-H_3 \)
• D. \( \text{R}-N-(CH_3)_2 \)

Hint:

LiAlH4 reduces nitriles to amines by adding hydrogen to the nitrile group.

Answer 1

The Correct Option is A

Step 1: LiAlH4 Reduction.
Lithium aluminium hydride (LiAlH4) is a strong reducing agent and can reduce nitriles (R-C≡N) to primary amines (R-NH2).
Step 2: Conclusion.
The correct answer is (A), \( \text{R}-NH_2 \).
