A) sodium atoms
B) sodium hydride
C) sodium amide
D) solvated electron
Correct Answer: D
Solution :
All alkali metals are soluble in liquid ammonia. \[Na+(x+y)N{{H}_{3}}\xrightarrow{{}}\underset{\begin{smallmatrix} ammoniated \\ cation \end{smallmatrix}}{\mathop{N{{a}^{+}}{{(N{{H}_{3}})}_{x}}}}\,+\underset{\begin{smallmatrix} ammoniated \\ electron \end{smallmatrix}}{\mathop{{{e}^{-}}{{(N{{H}_{3}})}_{y}}}}\,\] Due to presence of ammoniated electrons, sodium metal in liquid ammonia is a strong reducing agent.
