Chemistry Question on GROUP 1 ELEMENTS

When sodium is dissolved in liquid ammonia, a solution of deep blue colour is obtained. The colour of the solution is due to

A

ammoniated electron

B

sodium ion

C

sodium amide

D

ammoniated sodium ion

Answer

ammoniated electron

Explanation

Solution

The blue colour of the solution is due to the ammoniated electron which absorbs energy in the visible region of light and thus imparts blue colour to the solution. M+(x+y)NH3→[M(NH3)x]++[e(NH3)y]−M+\left(x+y\right)NH_{3} \to\left[M\left(NH_{3}\right)_{x}\right]^{+} +\left[e\left(NH_{3}\right)_{y}\right]^{-}
