Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R:

Assertion A: Metallic sodium dissolves in liquid ammonia giving a deep blue solution, which is paramagnetic.
Reasons R: The deep blue solution is due to the formation of amide.

In the light of the above statements, choose the correct answer from the options given below:

Aicharya · Accepted Answer

The alkali metals dissolve in ammonia to give a deep blue solution which is conducting in nature.

$M + (x + y) {NH}_{3} \to [M ({NH}_{3} )_{x} ]^{+} + [e ({NH}_{3} )_{y}]^{-}$

Due to the presence of ammoniated electrons, it is deep blue colour solution and paramagnetic in nature.

During the formation of amide, blue colour changes to bronze and paramagnetic nature changes to diamagnetic.
