NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Medium-Class 12
Consider an octahedral complex of cobalt in the +3 oxidation state with a coordination number of 6. If the complex is diamagnetic, what is the correct hybridization of the cobalt ion?
A
d2sp3
B
sp3d2
C
d3sp3
D
sp3
Correct Answer
Option A
Detailed Explanation
In a diamagnetic octahedral complex like [Co(NH3)6]3+, the cobalt ion undergoes d2sp3 hybridization, using inner d orbitals, resulting in no unpaired electrons.
