Answer 1

Let us consider the nature op compounds base ach & neutral dipperent solvents. in since all all are soluble organic compounds, they ethen. in - EP in base is popsent, it will discove dilute acid to form a water soluble salt R-NH₂ + the RH CT water soluble Salt But neutral compounds have no reaction with acid so they are insolu ble. To get the free base from the salt, we have to add a solution op another base (NaOH, which dissociates base & acid in salt.

R-NH₃ + NaOH R-NH2 + Nach +H2O This free base can be separated from Nacl solution by adding ether. R-NH2 + Nachttho Ether Insoluble souble R-NH₂ Nach + H2O Tither D Evoparation of Ether R-NH2. can be applied to This procedure the given binany mixture.
