Which of the following has highest molar conductivity

Options

A. Diaminedichloroplatinum (II)
B. Tetraaminedichlorocobalt (III) chloride
C. Potassium hexacyanoferrate (II)
D. Hexaaquochromium (III) bromide

Answer

C

Explanation

`K _(4) [Fe(CN)_6]`dissociates into five ions (maximum) `[Pt(NH_3)_2CL_(2) ]rightarrow` no ions
`([CO((NH_3)_4CL_(2)]Clrightarrow ` two ions `([Cr((NH_3)_6]) Br_(3)rightarrow` ions
`Fe(co)_5 rightarrow` no ions
