Which from following is a correct stability order of complex formed by metal ions if the ligand remains same?
Options
- AFe ²⁺ Mn ²⁺ Co ²⁺
- BCo ²⁺ Fe ²⁺ Mn ²⁺
- CCo ²⁺ Mn ²⁺ Fe ²⁺
- DFe ²⁺ Co ²⁺ Mn ²⁺
Correct answer
B. Co ²⁺ Fe ²⁺ Mn ²⁺
Step-by-step solution
The stability order of divalent metal ion complexes is given by Irving William series. Higher the charge to size ratio, greater is the stability of complex. Hence, the order is Co ²⁺ Fe ²⁺ Mn ²⁺ .
