Question : 40
Total: 43
Explain [Co(NH3)6]3+ is an inner orbital complex whereas [Ni(NH3)6]2+ is an outer orbital complex.
Solution:  
In the presence of NH3, the 3d electrons pair up leaving two d orbitalsempty to be involved in d2sp3hybridisation forming inner orbital complexin case of [Co(NH3)6]3+.
In [Ni(NH3)6]2+ , Ni is in +2 oxidation state and has d‌3configuration, thehybridisation involved is sp‌3d‌2forming outer orbital complex.
