    Let x be the O.N. of C.
    O.N. of C in cyanogen, (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 cyanate ion, CNO =x-3-2 = -l or x: = +4

    The four information about the reaction are:
    (i) The reaction involves decomposition of cyanogen, (CN)2 in the alkaline medium to cyanide ion, CN and cyanate ion, CNO–.

    (ii) The O.N. of C decreases from +3 in (CN)2 to +2 in CN–ion and increases from +3 in (CN)2 to +4 in CNO– ion. Thus, cyanogen is simultaneously reduced to cyanide ion and oxidised to cyanate ion.

    (iii) It is an example of a redox reaction in general an
