Question
Which among the following cations forms a least stable complex if the ligand is same?
Options
Fe2+
Ni2+
Cd2+
Co2+
MCQ
Solution
Cd2+
Explanation:
The electronic configuration of the given cations are as follows:
Fe2+ = 3d6, 4s0; Ni2+ = 3d8, 4s0
Cd2+ = 4d10, 5s0; Co2+ = 3d7, 4s0
Cd2+ ion has an orbital that is fully filled among the options provided. As a result, if the ligand is the same in all instances, there is very little chance that a stable compound would form.
