Which of the following reactions will NOT give primary amine as the product?
  1. CH3CONH2(ii) H3O+(i) LiAlH4Product
  2. CH3CONH2Br2/KOHProduct
  3. CH3CN(ii) H3O+(i) LiAlH4Product
  4. CH3NC(ii) H3O+(i) LiAlH4Product

Solution

Lithium aluminium hydride is a strong reducing agent. It converts amides, cyanides and isocyanides to amines.

CH3CONH2(ii) H3O+(i) LiAlH4CH3CH2NH2primary amine

CH3CN(ii) H3O+(i) LiAlH4CH3CH2NH2Primary amine

CH3NC(ii) H3O+(i) LiAlH4CH3NHCH3Secondary amine

In Hoffmann bromamide reaction, primary amides converts to primary amines with loss of one carbon.

CH3CONH2Br2/KOHCH3NH2
