Q. Which of the following reagents will be fruitful for separating a mixture of nitrobenzene and aniline?
A) Aq. NaHC$O_{3}$
B) $H_{2}O$
C) Aq. HCl
D) Aq. NaOH
Explanation
(c)
The reagent selected should be such that only one of components to be separated, reacts with it.
Aniline+aq. HCl$\rightarrow$salt, which is water soluble
Nitrobenzene +aq. HCl$\rightarrow$no reaction
∴ aq. HCl is used to separate aniline and nitrobenzene.
