Which one of the following complexes in an outer orbital complex?

[Fe(CN)₆]^4-

[Ni(NH₃)₆]²⁺

[Co(NH₃)₆]³⁺

[Mn(CN)₆]^4-

Correct Answer:

Hybridisation

\mathop {{{\left[ {Fe{{\left( {CN} \right)}_6}} \right]}^{4 - }},}\limits_{{d^2}s{p^3}} \,\,\mathop {{{\left[ {Mn{{\left( {CN} \right)}_6}} \right]}^{4 - }},}\limits_{{d^2}s{p^3}}

\mathop {{{\left[ {Co{{\left( {N{H_3}} \right)}_3}} \right]}^{3 + }},}\limits_{{d^2}s{p^3}} \,\,\mathop {{{\left[ {Ni{{\left( {N{H_3}} \right)}_6}} \right]}^{2 + }}}\limits_{s{p^3}{d^2}}

Hence

{\left[ {Ni{{\left( {N{H_3}} \right)}_6}} \right]^{2 + }}

is outer orbital complex.
