Q51.An octahedral complex of Co3+ is diamagnetic. The hybridisation involved in the formation of the complex is : (1) dsp2 (2) d2sp3 (3) dsp3d (4) sp3d2
What This Question Tests
This question tests the understanding that a diamagnetic octahedral Co³⁺ complex implies all electrons are paired, leading to an inner orbital (d²sp³) hybridization with strong field ligands.
