    Which one of the following has the highest molar conductivity?

    A)  Diamine dichloroplatinum (II)

    B)  Tetraamine dichlorocobalt (III) chloride

    C)  Potassium hexacyanoferrate (II)

    D)  Pentacarbonyl iron (O)

    Correct Answer: C

    Solution :

    Potassium hexa cyanoferrate (II) i.e. \[{{K}_{4}}[Fe{{(CN)}_{6}}]\] gives the maximum number of ions on ionisation hence it has the highest molar conductivity. \[{{K}_{4}}\left[ Fe{{(CN)}_{6}} \right]\xrightarrow{{}}4{{K}^{+}}+{{\left[ Fe{{(CN)}_{6}} \right]}^{4-}}\]
