Answer 2

The force which responsible for the formation of ammoniated sodium ion is : 2) Ion - dipole

• For the formation of ammoniated ion ,the force responsible is ion-dipole interaction .

• As, NH3 has dipole moment as there is polarity in the bond due to electronegativity difference. So, when sodium metal is dropped in liquid NH3 , the sodium metal ion will interact with liquid NH3 which has dipole moment . Thus, it will form the ion - dipole interaction.

• While , in ammonia molecules only there is intermolecular hydrogen bonding exists , means among the NH3 molecules .
