Electrical conductivity of the complexes is directly proportional to the number of ions (n) produced
The dissociation of given complexes can be shown as,

[N i (N H_{3})_{4} C l_{2}] \to

No ions

[CO (N H_{3})_{4} C l_{2}] Cl \to [C o (N H_{3})_{4} C l_{2}]^{+} + C l^{-}; (n = 2)

K_{2} [PtC l_{6}] \to 2 K^{+} + [ptC l_{6}]^{2 -}; (n = 3)

K_{4} [F e (CN)_{6}] \to 4 K^{+} + [F e (CN)_{6}]^{4 -}; (n = 5)

Thus, the increasing order of electrical conductivity is:

[N i (N H_{3})_{4} C l_{2}] < [C o (N H_{3})_{4} C l_{2}] Cl < K_{2} [PtC l_{6}] < K_{4} [F e (CN)_{6}]
