Identify the major product C formed in the following reaction sequence : CH3-CH2-CH2-I NaCN A [Partial hydrolysis]OH- B [Br2]NaOH (major)C

  1. propylamine
  2. butylamine
  3. butanamide
  4. -bromobutanoic acid

Answer

(1) propylamine

Solution

CH3CH2CH2I + NaCN CH3CH2CH2CN (A, butanenitrile)

Partial hydrolysis: CH3CH2CH2CN OH- CH3CH2CH2CONH2 (B, butanamide)

Hoffmann bromamide degradation (one carbon less): CH3CH2CH2CONH2 Br2/NaOH CH3CH2CH2NH2

C is propylamine.
