Correct order of polarising power is
Options
- ACs ⁺ K ⁺ Mg ²⁺ Al ³⁺
- BK ⁺ Cs ⁺ Mg ²⁺ Al ³⁺
- CMg ²⁺ Al ³⁺ K ⁺ Cs ⁺
- DMg ²⁺ Al ³⁺ Cs ⁺ K ⁺
Correct answer
A. Cs ⁺ K ⁺ Mg ²⁺ Al ³⁺
Step-by-step solution
Polarising power is determined by charge/size ratio. Higher charge and smaller size gives more polarising power. Thus, the correct order is Cs ⁺ K ⁺ Mg ²⁺ Al ³⁺
