All Cu(II) halides are known except the iodide. The reason for it is thatA. iodide is a bulky ionB. `Cu^(2+)` oxidizes iodide to iodineC. `Cu_((aq))^(2+)` has much negative hydration enthalpyD. `Cu^(2+)` ion has smaller size.

Answer» Correct Answer - B
`2Cu^(2+)+4I^(-)to 2CuI_2`
The `CuI_2` immediately decomposes to liberate `I_2` and insoluble copper (I) iodide.
`2CuI_2to 2CuI+I_2`
