Vedclass · Answer

(B) Alkali metals dissolve in liquid ammonia to form a deep blue solution.This blue color is primarily due to the presence of ammoniated (solvated) electrons,which absorb energy in the visible region of the spectrum.$STATEMENT-1$ is True.$STATEMENT-2$ is also True because alkali metals do form solvated cations $[M(NH_3)_n]^{+}$ and solvated electrons $[e(NH_3)_x]^{-}$.However,the blue color is specifically attributed to the solvated electrons,not the solvated metal cations.Therefore,$Statement-2$ is not the correct explanation for $Statement-1$.

$STATEMENT-1$: Alkali metals dissolve in liquid ammonia to give a blue solution because
$STATEMENT-2$: Alkali metals in liquid ammonia give solvated species of the type $[M(NH_3)_n]^{+}$ ($M=$ alkali metals).
