    The coordination number and oxidation number of X in the following compound \[[\,X(S{{O}_{4}}){{(N{{H}_{3}})}_{5}}]Cl\] will be

    A)  10 and 3                             

    B)  2 and 6

    C)  6 and 3                                

    D)  6 and 4

    Correct Answer: C

    Solution :

                     Coordination number is the number of ligands o-bonded to metal atom. Hence, coordination number of X in \[[X\,(S{{O}_{4}})\,{{(N{{H}_{3}})}_{5}}]Cl\] is 6. Let oxidation state of X in the complex be y, then                 Y + (-2) + 5(0) + (-1) = 0                                 Y - 2 - 1 = 0                                                 Y = + 3
