To separate a mixture of p-toluidine and p-nitrotoluene dissolved in ether,extract the ether solution with aqueous HCl and treat the water layer with aqueous NaOH.

Question

Quizplus · Accepted Answer

The process described utilizes the principle of acid-base extraction. p-Toluidine, being a base, reacts with HCl to form a water-soluble salt, thus moving into the aqueous layer, while p-nitrotoluene remains in the ether layer due to its lack of reactivity with HCl. Treating the aqueous layer with NaOH then regenerates the p-toluidine by deprotonation, allowing for its separation from p-nitrotoluene.
