lectronic configuration of ( Cu ( II ) ) is (3 ~d ^9 ) whereas that of ( Cu ( I ) ) is (3 ~d ¹⁰ ). Which of the following is correct?
Options
- AStability of ( Cu ( I ) ) and ( Cu ( II ) ) depends on nature of copper salts
- B( Cu ( II ) ) is more stable
- C( Cu ( I ) ) and ( Cu ( II ) ) are equally stable
- D( Cu ) (II) is less stable
Correct answer
B. ( Cu ( II ) ) is more stable
Step-by-step solution
Cu ( II ) is more stable than Cu ( I ) because hydration energy of Cu ⁺² ion compensate IE ₂ of Cu .
