Chemistry Question on coordination compounds

Which of the following will exhibit maximum ionic conductivity?

A

K4[Fe(CN)6]K_4[Fe(CN)_6]

B

[Co(NH3)6]Cl3[Co(NH_3)_6]Cl_3

C

[Cu(NH3)4]Cl2[Cu(NH_3)_4]Cl_2

D

[Ni(CO)4][Ni(CO)_4]

Answer

K4[Fe(CN)6]K_4[Fe(CN)_6]

Explanation

Solution

Ionic conductivity depends upon the number of ions produced in aqueous solution. K4[Fe(CN)6]K_4[Fe(CN)_6] produces maximum number of ions, i.e. 5
4K++[Fe(CN)6]4−⏟Total 5 ions\underbrace{ 4K^++ [Fe(CN)_6]^{4-} }_{Total\, 5\, ions}
