    The sum of coordination number and oxidation number of the metal M in the complex \[[M{{(en)}_{2}}({{C}_{2}}{{O}_{4}})]Cl\] (where, en is ethylenediamine) is                                                                                        

    A)  9                            

    B)  6                            

    C)  7                            

    D)  8

    Correct Answer: B

    Solution :

    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.
