Question

A solution of m-chloroaniline, m-chlorophenol and m-chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of $\mathrm{NaHCO}_3$ 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 $\mathrm{A}, \mathrm{B}$ and C , contain respectively:

Select the correct option:

A

m-chloroaniline, m-chlorobenzoic acid and m-chlorophenol

B

m-chlorophenol, m-chlorobenzoic acid and m-chloroaniline

C

m-chlorobenzoic acid, m-chlorophenol and m-chloroaniline

D

m-chlorobenzoic acid, m-chloroaniline and m-chlorophenol

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.
