Which among the following cations will form lowest stability complex if the ligand remains the same?

Options

  1. ACu ²⁺
  2. BFe ²⁺
  3. CCd ²⁺
  4. DNi ²⁺

Correct answer

C. Cd ²⁺

Step-by-step solution

The stability of metal complex increases with decrease in size of the metal cations. Cd ²⁺ has highest size among given cations, so it will form lowest stability complex
