    Which of the following exhibits highest molar  conductivity?

    A)  \[[Co{{(N{{H}_{3}})}_{6}}]C{{l}_{3}}\]

    B)  \[[Co{{(N{{H}_{3}})}_{5}}Cl]C{{l}_{2}}\]

    C)  \[[Co{{(N{{H}_{3}})}_{4}}C{{l}_{2}}]Cl\]

    D)  \[[Co{{(N{{H}_{3}})}_{3}}C{{l}_{3}}]\]

    Correct Answer: A

    Solution :

    Molar conductivity of any compound depends on the total number of free ions. As \[[Co{{(N{{H}_{3}})}_{6}}]C{{l}_{3}}\] has maximum number of ions, so its molar conductivity will be highest. In this compound, total number of ions \[=4\]
