Question

Alkali metal superoxides are obtained by the reaction of (A) oxygen with alkali metals in liquid ammonia (B) water with alkali metals in liquid ammonia (C) H2O2 with alkali metals (D) H2O2 with alkali metals in liquid ammonia

Tardigrade Admin · Accepted Answer

Alkali metals in liquid ammonia produce solvated electrons

alkali metal M + (x + y) N H_{3} \to Ammoniated metal ion [M (N H_{3})]^{+} + Ammoniated electron [e (N H_{3})]^{-}

Solvated electrons can reduce

O_{2}

molecule to superoxide ion.

[e (N H_{3})_{y}]^{-} + \to Superoxide ion O_{2}^{-} +_{y} N H_{3}

These superoxide ions can combine with solvated metal ion to give alkali metal superoxide

[M (N H_{3})_{x}]^{+} + O_{2}^{-} \to alkali metal superoxide M O_{2} +_{x} N H_{3}
