As we learned

Effective Atomic Number (EAN) -

EAN=\left ( Z-x \right )+2\times C.N.

- wherein

Z= Atomic  Number of Center Atom

x= Oxidation Number

C.N. =Coordination Number

 

 EAN of  Pt\; \; in\; \; [PtCl_{6}]^{2-}=80

 


Option 1)

Effective atomic number of Pt\; \; in \; \; [PtCl_{6}]^{2-}=84                                   

Option 2)

Absorption peak for  \left [ Cr^{III}(NH_{3})_{6} \right ]^{+3}=21680cm^{-1}

Option 3)

Crystal field stabilization energy of  d^{2} in weak ligand field  =(-)0.8\bigtriangleup _{0}

Option 4)

Example of weak ligand field for d^{5} configuration =\left [ Mn^{II}F_{6^} \right ]^{-4}
