    The correct order of the stoichiometries of AgCl formed when\[AgN{{O}_{3}}\]in excess is treated with the complexes : \[CoC{{l}_{3}}.6N{{H}_{3}},CoC{{l}_{3}}.5N{{H}_{3}},CoC{{l}_{3}}.4N{{H}_{3}}\] respectively is                           [NEET-2017]

    A) \[2\,AgCl,3AgCl,\,1\,AgCl\]

    B)                               \[1\,AgCl,3AgCl,\,2\,AgCl\]

    C) \[3\,AgCl,1AgCl,\,2\,AgCl\]

    D) \[3\,AgCl,2AgCl,\,1\,AgCl\]

    Correct Answer: D

    Solution :

    [d] Complexes are respectively\[[Co{{(N{{H}_{3}})}_{6}}]C{{l}_{3}}\]            \[[Co{{(N{{H}_{3}})}_{5}}Cl]C{{l}_{2}}\]and \[[Co{{(N{{H}_{3}})}_{4}}]Cl\]
