Alkali metals M dissolve in liquid NH 3 to give
Options
- AMNH 2
- BMH
- CM NH 3 x + + e NH 3 y -
- DM 3 N
Correct answer
C. M NH 3 x + + e NH 3 y -
Step-by-step solution
When alkali metals are dissolved in liquid ammonia, they exist in solution as ammoniated cations after releasing valence electrons, and the released electrons also stay in solution in an ammoniated state. Ammoniation is solvation by ammonia.
