Which of the following will exhibit maximum ionic conductivity?

Options

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

Answer

A

Explanation

`K_4[Fe(CN)_6](aq) hArr 4K^+ (aq) + [Fe(CN)^(4-)(aq)`
It gives five 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.
