A solution of m - chloroaniline, m - chlorophenol and m - chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of N a H C O 3 to give fraction A . The left over organic phase was extracted with dilute N a O H solution to give fraction B . The final organic layer was labelled as fraction C . Fractions A , B and C , contain respectively:
Options
- Am - chlorobenzoic acid, m - chloroaniline and m - chlorophenol
- Bm - chlorobenzoic acid, m - chlorophenol and m - chloroaniline
- Cm - chlorophenol, m - chlorobenzoic acid and m - chloroanilinc
- Dm - chloroaniline, m - chlorobenzoic acid and m - chlorophenol
Correct answer
B. m - chlorobenzoic acid, m - chlorophenol and m - chloroaniline
Step-by-step 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.
