JEE MAIN - Chemistry (2020 - 7th January Morning Slot - No. 17)
A solution of m-chloronailimne, m-chlorophenol and m-chlorobenzoic acid in ethyal 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 tio give fraction B. The final organiic layer was labelled as
fraction C. Fractions A,B and C, contain respectively :
m-chlorobenzoic acid, m-chloroaniline and m-chlorophenol.
m-chlorobenzoic acid, m-chlorophenol and m-chloroaniline.
m-chlorophenol, m-chlorobenzoic acid and m-chloronailine.
m-chloroaniline m-chlorobenzoic acid and m-chlorophenol.
Explanation
m-chlorobenzoic acid dissolves in aq NaHCO3
while m-chlorophenol dissolves in aq NaOH.
