Hi,

Here is your answer,

→ The mixture is treated with dil. HCL. Only aniline dissolves. It is then shaken with ether. Nitrobenzene goes into ether layer. It is separated.

→ Nitrobenzene is obtained by evaporating ether.

→ The aqueous layer, on neutralisation with NaOH gives aniline. It is also shaken with ether separately and ether is collected. Aniline is obtained by evaporating ether.


Hope it helps you !

hey!!!

HERE IS YOUR ANSWER!!!

NITROBENZENE HAVE PRIMARY NITROGEN GROUP (NO2)
Aniline have primary ammonium group (Nh3)

as we can differentiate these two with the HELP OF

CARBALAMINE TEST AS IT IS A TEST USED TO DIFFERENTIATE PRIMARY WITH SECONDARY AMINE

SO ANILINE IS POSITIVE FOR THIS TEST

HOPE IT WILL HELP YOU!!!
