(D) When alkali metals (Group $1$) dissolve in liquid ammonia,they form deep blue solutions due to the presence of ammoniated electrons. These solutions are paramagnetic and conduct electricity.When alkaline earth metals (Group $2$) dissolve in liquid ammonia,they also form blue solutions,but the rate of decomposition is generally faster compared to Group $1$ metals.However,the most significant difference lies in the products obtained upon evaporation of the solvent. Group $1$ metals typically yield the original metal upon evaporation of ammonia,whereas Group $2$ metals form ammoniates of the type $[M(NH_3)_6]^{2+}$.

Metal-ammonia solutions of group $1$ and group $2$ metals differ in
