Phenol and benzoic acid is separated by :

Options

A. `NaHCO_(3)`
B. `NaOH` solution
C. `FeCl_(3)` solution
D. All of these

Answer

A

Explanation

Phenol does not react with `NaHCO_(3)` whereas benzoic acid will react to form sodium salt which can be hydrolysed to get benzoic acid back.
(b) Both will react with NaOH, therefore `NAOH` cannot be used for separation.
(c ) Phenol forms complex with `FeCl_(3)` from which phenol cannot be recovered, therefore cannot be used.
(d ) is not possible,
