Primary, secondary and tertiary amines can be separated using:

Options

  1. APara-Toluene sulphonyl chloride
  2. BChloroform and KOH
  3. CBenzene sulphonic acid
  4. DAcetyl amide

Correct answer

A. Para-Toluene sulphonyl chloride

Step-by-step solution

Primary amines react with Para-toluene sulphonyl chloride to form a precipitate that is soluble in NaOH . Secondary amines reacts with Para-toluene sulphonyl chloride to give a precipitate that is insoluble in NaOH . Tertiary amines do not react with Para-toluene sulphonyl chloride.
