As we have learned

CFSE in tetrahedral complexes -

CFSE = \left [-\frac{3}{5}\left ( No.\;of\;electron\;in\;e \right )+\frac{2}{5}\left ( No.\;of\;\acute{e}\;in\; t_{2}\right ) \right ] \bigtriangleup t

-

 

 [Ni(CN)_4]^2- has geometry square planar while other has tetrahedra

 


Option 1)

[Ni Cl_4]^{2-}

Option 2)

Ni(CO)_4

Option 3)

[Ni (CN)_4]^{2-}

Option 4)

[Zn(NH_3)_4]^{2+}
