• question_answer 30) What sorts of information can you draw from the following reaction?

In ${{(CN)}_{2}}$, oxidation state of carbon will be: $2x-6=0,\,$ $x=+3$ Similarly in$C{{N}^{-}}$, $x-3=-1,$ $x=+2$ $CN{{O}^{-}},$ $x-3-2=-1,$ $x=+4$ The reaction shows disproportionation in which cyanogen ${{(CN)}_{2}}$ is reduced to $(C{{N}^{-}})$ and oxidised to $(C{{N}^{-}})$ion.
