    What is the magnetic moment (spin only) and hybridisation of the brown ring complex \[\left[ Fe{{\left( {{H}_{2}}O \right)}_{5}}NO \right]S{{O}_{4}}\]?

    A) \[\sqrt{3}BM,s{{p}^{3}}{{d}^{2}}\]   

    B) \[\sqrt{3}BM,{{d}^{2}}s{{p}^{3}}\]

    C) \[\sqrt{15}BM,s{{p}^{3}}{{d}^{2}}\]            

    D) \[\sqrt{15}BM,{{d}^{2}}s{{p}^{3}}\]

    Correct Answer: C

    Solution :

    [c] Number of unpaired electrons = 3 \[{{\mu }_{eff}}=3.9BM\] type of hybridisation \[=s{{p}^{3}}{{d}^{2}}\]
