1)

$R-NC$     $\underrightarrow{LiAlH_{4}}$   P

 The product P in this reaction is 


A) $R-NH_{2}$

B) $R-NH-CH_{3}$

C) $R-CH_{3}$

D) $R-N-(CH_{3})_{2}$

Answer:

Option B

Explanation:

 Isonitriles on reductiobn with Li AlH4 give 2° amines

$R-N\overrightarrow{=}C$   $\underrightarrow{LiAlH_{4}}$  RNHCH3
