Which of the following will exhibit maximum ionic conductivity?

Options

A. (a) `[Co(NH_3)_6]Cl_3`
B. (b) `[Cu(NH_3)_4]Cl_2`
C. (c) `[Ni(CO)_4]`
D. (d) `K_4[Fe(CN)_6]`

Answer

D

Explanation

`K_4[Fe(CN)_6](aq)hArr4K+ (aq)+[Fe(CN)^(4-)(aq)]` It gives ions in solution.
`[Co(NH_(3))_6]Cl_3 (aq)hArr [Co(NH_(3))_(6)](aq)+3Cl^(-)(aq)` It gives four ions in solution.
`[Cu(NH_3)_4]Cl_(2) (aq) hArr [Cu(NH_(3))_(4)]^(2+) (aq) + 2Cl^(-) (aq)` It gives three ions in solution.
