Question

All Cu(II) halides are known, except the iodide, the reaction for it is that (A) Cu +2 has much more negative hydration enthalpy (B) Cu +2 ion has smaller size (C) Iodide is bulky ion (D) Cu +2 oxidises iodide to iodine

Tardigrade Admin · Accepted Answer

Correct answer is (d) Cu +2 oxidises iodide to iodine

Q. All $C u (II)$ halides are known, except the iodide, the reaction for it is that

$C u^{+ 2}$ has much more negative hydration enthalpy

$C u^{+ 2}$ ion has smaller size

Iodide is bulky ion

$C u^{+ 2}$ oxidises iodide to iodine

Correct answer is (d) $C u^{+ 2}$ oxidises iodide to iodine

Q. All Cu(II) halides are known, except the iodide, the reaction for it is that

Cu+2 has much more negative hydration enthalpy

Cu+2 ion has smaller size
