(D) When alkali metals dissolve in liquid ammonia,they undergo the following reaction: $M + (x+y)NH_3 \rightarrow [M(NH_3)_x]^+ + e^-(NH_3)_y$. The blue colour of the solution is due to the excitation of ammoniated electrons to higher energy levels by absorbing red light. The solution is highly conducting due to the presence of both ammoniated cations $[M(NH_3)_x]^+$ and ammoniated electrons $e^-(NH_3)_y$.

Metals dissolve in liquid ammonia giving coloured solutions which are conducting in nature. The colour of the solution and reason of its conductance is
