Question
On dissolving moderate moderate amount of sodium metal in liquid NH3 at low temperature, which one of the following does not occur?
Options
A.Blue coloured solution is obatained
B.N+ ions are formed in the solution
C.Liquid NH3 becomes good conductor of electricity
D.Lipid ammonia remains diamagnetic
Solution
Sodium dissolves in liquid ammonia to form blue solution which is good conductor ofelectricity. The blue color of the solution is due to formation of ammonites electrons.
Na → Na+ + e-
Na+ + xNH3 → Na+ (NH3)x
e- + yNH3 → [e(NH3)y]
ammoniated electron
Due to presence of unpaired lectron liquid ammonia become paramagnetic electron liquidammonia become paramagnetic.
