All Cu(II) halides are known except the iodide. The reason for is that

Answer»

iodine is a bulky ion
`Cu^(2+)` oxidizes iodideto iodine
`Cu^(2+)` has MUCH more negative hydration enthalpy
`Cu^(2+)` ion has SMALLER size

Solution :`2Cu^(2+) + 4I^(-) to 2CuI_(2)`
`2CuL_(2)` immediately DECOMPOSES to give `I_(2)` and INSOLUBLE copper (I) iodide.
