MCQ
ll Cu(II) halides are known except the iodide. The reason for it is that:
- Aiodide is a bulky ion.
- BCu2+ oxidizes iodide to iodine.
- C$\text{Cu}^{2+}_\text{(aq)}$ has much more negative hydration enthalpy.
- DCu2+ ion has smaller size.

- Cu2+ oxidizes iodide to iodine.
Explanation:
All Cu(II) halides are known except the iodine because Cu2+ oxidizes iodine to iodine.
2Cu2++ 4I−1 → 2CuI(S) + I2.
