On dissolving moderate amount of sodium metal in liquid ammonia at low temperature, which of the following does not occur ?

Options

A. Blue coloured solution is obtained
B. `Na^+` ions are formed in the solution
C. Liquid `NH_3` becomes good conductor of electricity
D. Liquid ammonia remains diamagnetic.

Answer

D

Explanation

The alkali metals dissolve in liquid ammonia without evolution of hydrogen. The colour of the dilute solution is blue and are paramagnetic in nature.
`M to M^(+)` (in liquid ammonia ) + `e^(-)` (ammoniated )
`M+(x+y)NH_3 to [M(NH_3)_x]^(+) + e^(-) (NH_3)_3` solvent electron
