Text Solution

Verified by Experts
The correct answer is:
A

[Ni(NH3)6]2+ has sp3d2 hybridisation having octahedral geometry as with d8 configuration no two empty d-orbitals are available for d2sp3 hybridisation. As sp3d2 hybridisation involves nd orbital (i.e. outer orbitals), so the complex is called as outer orbital complex.
