All alkali metals dissolve in anhydrous liquid ammonia to give blue colour solution. It is the ammoniated electron which is reponsible for the blue colour of the solution, and the electrical conductivity is due to the ammoniated cation, `[M(NH_(3))_(x)]^(+)` as well as the ammoniated electron,` [e(NH_(3))_(y)]^(-)`, value of x and y depend on the extent of solvation by `NH_(3)`. Dilute solutions are paramagnetic due to free ammoniated electrons.
Q. Which of the following statement about solution of alkali metals in liquid ammonia is correct?

Options

A. The solution has strong oxidizing properties
B. Both the dil. Solution as well as conc. Solution are equally paramagnetic in nature
C. Charge transfer is responsible for the colour of the solution
D. None of these

Answer

D

Explanation

All are wrong. The solution has stronng reducing nature and coloured due to ammoniated electron.
