The number of unpaired electrons in the complex ion \({[Co{F_6}]^{3 - }}\) is (Atomic no. of \(Co = 27)\)
1 \(0\)
2 \(2\)
3 \(3\)
4 \(4\)
Explanation:
(d) The number of unpaired electrons in the Complex ion \({[Co{F_6}]^{3 - }}\) is \(4.\)
Coordination isomerism is a form of structural isomerism in which the composition of the complex ion varies. In a coordination isomer the total ratio of ligand to metal remains the same, but the ligands attached to a specific metal ion change. Examples of a complete series of coordination isomers require at least two.
