    The EAN of Zn in \[{{[Zn{{(OH)}_{4}}]}^{2-}}\] complex is:

    A)  16                                         

    B)  26                                         

    C)  36                         

    D)         46

    Correct Answer: C

    Solution :

    Effective atomic number (BAN) for any complex ion \[=Z-O.\text{ }N.+2(C.\text{ }N.)\] Z = atomic number of central metal atom/ion O.N. = oxidation number of central metal atom/ion C.N. = co-ordination number of central metal atom In  \[{{[Zn{{(OH)}_{4}}]}^{2-}}\] \[\therefore \]   \[Z=30,O.N.=+2,C.N.=4\] \[EAN=\text{ }30-2+2\times 4\] \[=36\]
