  • question_answer
    Which of the following has highest molar conductivity?

    A) Diamminedichloro platinum (II)

    B) Tetraammined Jchlorocobalt (III) chloride

    C) Potassium hexacya no ferrate (II)

    D) Pentacarbonyliron (0)

    Correct Answer: C

    Solution :

    [c] : \[{{K}_{4}}[Fe{{(CN)}_{6}}]\rightleftharpoons 4{{K}^{+}}+{{[Fe{{(CN)}_{6}}]}^{4-}}\] Potassium hexacyanoferrate (II) gives a total of 5 ions in aqueous solution thus, it has the highest molar conductivity whereas other complexes will give lesser number of ions.
