What sort of informations can you draw from the following reaction?
`(CN)_(2)(g) + 2overset(Θ)(OH)(aq) rarrCN^(Θ)(aq)+CNO^(Θ)(aq) + H_(2)O(l)`

Explanation

Let x be the O.N of C `therefore` O.N of c in cayanogen `(cn)_(2)=2(x-3)=0 or x=+3`
O.N of C in cyanide ion `CN^(-)=x-3=-1 or x =+2`
O.N of C in cyantate ion CND = x-3 -2 =- 1 or x=-4
The following four information can be drawn from the above reaction
(i) the reaction in volved decompostion of cyanogen `(CN)_(2)` to +2 in `CN^(-)` ion and increases from +3 in `(CN)_(2)` to +4 is `CNO^(-)` ion of C thus cyangoen is simultaneously reduced to caynide ion andd oxidised to cyantate ion
(iii) it is an example of a redox reaction and a disportination in particular (iv) cyanogen is a pseudohalogen (behave like halogens) while cyanide ions is a peseudhalide ion (behave like halide ion)
