Which of the following statements about primary amines is ‘False’?

  1. A
    Alkyl amines are stronger bases than ammonia
  2. B
    Alkyl amines are stronger bases than aryl amines
  3. C
    Alkyl amines react with nitrous acid to produce alcohols
  4. D
    Aryl amines react with nitrous acid to produce phenols

Solution & Step-by-step Explanation

Primary aromatic amines (aryl amines) react with nitrous acid at low temperature to form diazonium salts. They do not directly produce phenols under those conditions (it requires subsequent heating with water). Primary aliphatic amines produce unstable diazonium salts that decompose immediately to form alcohols.Statement D is false.
