Question:
The number of unpaired electrons in \([CoF_6]^{3-}\) is:
The number of unpaired electrons in \([CoF_6]^{3-}\) is:
Show Hint
Weak field ligands do not cause electron pairing, leading to a higher number of unpaired electrons in the d-orbital.

- one
- four
- zero
- two
- three
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In \([CoF_6]^{3-}\), cobalt is in the +3 oxidation state, which corresponds to a \(3d^6\) electron configuration. Since fluoride is a weak field ligand, it does not induce strong electron pairing. The electrons remain unpaired, leading to a total of four unpaired electrons.
