Question

In hydrolysis of aniline, the reagent used is

  1. Dil. HCl    
  2. Acetyl chloride    
  3. C H subscript 3 end subscript O H    
  4. None of these    

The correct answer is: Dil. HCl


    All amines react with mineral acids such as H C l, H subscript 2 end subscript S O subscript 4 end subscript comma H N O subscript 3 end subscript etc. to form salts which are soluble in water.
