Answer» Solution :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)
