A solution of m- chloroaniline, m- chlorophenol and m- chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of NaHCO3 to give fraction A . The left over organic phase was extracted with dilute NaOH solution to give fraction B . The final organic layer was labelled as fraction C . Fractions A,B and C, contain respectively:
  1. m- chlorobenzoic acid, m- chloroaniline and m- chlorophenol
  2. m- chlorobenzoic acid, m- chlorophenol and m- chloroaniline
  3. m- chlorophenol, m- chlorobenzoic acid and m- chloroanilinc
  4. m- chloroaniline, m- chlorobenzoic acid and m- chlorophenol

Solution

Here are some of the important methods which are commonly employed for the purification of organic compounds:
Filtration.
Crystallisation or Recrystallisation.
Fractional Crystallisation.
Sublimation.
Simple Distillation.
Fractional Distillation.
Distillation under reduced pressure or Vacuum Distillation.
