    The oxidation state of Fe in the brown ring complex:\[[Fe{{({{H}_{2}}O)}_{5}}NO]S{{O}_{4}}\]is

    A)  +3                                                                         

    B)                    0

    C)         +2                                         

    D)         +1

    Correct Answer: D

    Solution :

    Let the oxidation state of\[Fe\]in\[[Fe{{({{H}_{2}}O)}_{5}}NO]S{{O}_{4}}\]is\[x\].                 \[{{[Fe{{({{H}_{2}}O)}_{5}}NO]}^{2+}}\] \[\Rightarrow \]               \[x+0+1=2\] \[\therefore \]  \[x=+1\] Here\[NO\]exists as nitrosyl ion\[(N{{O}^{+}})\].
