Aniline can be separated from phenol using

Answer»

`Na_(2)CO_(3)`
`NaNO_(2)+ HCl` at `0^(@) C`
`NaCl`
Acidified `KMnO_(4)`

Solution :Aniline and phenol can be separated by adding `NaNO_(2) + HCl` as aniline forms DIAZONIUM salt anilinium chloride, while phenol does not. Hence, choice (b) is correct. Choice (a) is INCORRECT because `Na_(2)CO_(3)` NEITHER reacts with aniline nor with phenol. Choice (c ) is incorrect because `NaCl` does not REACT withphenol. Choice (d) is incorrectbecause `KMnO_(4)` oxidies both aniline and phenol.
