    Iron carbonyl, ``Fe(CO)_5`` is
    (1) tetranuclear
    (2) mononuclear
    (3) trinuclear
    (4) dinuclear
    digAnsr:   2
    Ans : (2)
    Sol. Fe(CO)5
    EAN = Z-O.N. + 2(C.N.)
    = 26 - 0 + 2(5)
    = 26 + 10
    = 36
    only one central metal atom/ion is present and it
    follows EAN rule, so it is mononuclear
