    The sum of coordination number and oxidation number of the metal M in the complex  (where, en is ethylenediamine) is               [NEET 2015 (Re)]

    A) 9

    B) 6

    C) 7

    D) 8

    Correct Answer: B

    Solution :

    [b] Given complex compound is \[[M{{(en)}_{2}}({{C}_{2}}{{O}_{4}})]Cl\]
    Let oxidation number of M is x
    \[\therefore \]                \[x-2-2=-1\]
    or                 x = + 3
    Now as coordination number is defined as the total number of binding sites attached to the metal. Hence, in the given complex coordination number is 6.
