Which of the following options describes a method used for the identification of primary, secondary and tertiary amines correctly?

Options

  1. AIn the Hinsberg Test, the amines act as nucleophiles and attack the electrophile (sulphonyl chloride). This le
  2. BThe Hinsberg test is a quantitative test used to determine the concentration of amines in a solution.
  3. CThe Hinsberg test is a method for the synthesis of amines from aromatic compounds.
  4. DThe Hinsberg test is a titration method used to measure the acidity of amines.

Correct answer

A. In the Hinsberg Test, the amines act as nucleophiles and attack the electrophile (sulphonyl chloride). This le

Step-by-step solution

Correct Option is : (A) In the Hinsberg Test, the amines act as nucleophiles and attack the electrophile (sulphonyl chloride). This leads to the displacement of the chloride and the generation of the sulphonamides.Primary amine sulphonamides are soluble in alkali whereas secondary amine sulphonamides are not soluble in alkali.No such reaction takes place for tertiary amines.
