An octahedral complex of Co 3 + is diamagnetic. The hybridisation involved in the formation of the complex is :
Options
- Adsp 2
- Bd 2 sp 3
- Cdsp 3 d
- Dsp 3 d 2
Correct answer
B. d 2 sp 3
Step-by-step solution
2 7 Co 3 + has 24 Electrons i.e 6 electrons in inner 3d orbital of central metal ion for diamagnetic behaviour these d 6 Electrons have to be paired and due to pairing two inner d-orbitals get empty and hybridisation is d 2 sp 3 .
