Question

Which of the following is an outer orbital complex?

Solution

Correct option is

[Co(NH3)6]3+

 

[Fe(CN)6]4– : Fe (II) – 3d6 ; inner orbital complex (d2sp3) ; n = 0 

[Mn(CN)6]4– : Mn (II) – 3d5 ; inner orbital complex (d2sp3) ; n = 1 

[Co(NH3)6]3+ : Co (III) – 3d6 ; inner orbital complex (d2sp3) ; n = 0

[Ni(NH3)6]2+ : Ni (II) – 3d8 ; NH3, a strong ligand, cannot make two 3d-orbitals available by forcing the electrons paired up. Hence, outer orbital complex (sp2d2) ; n = 2
