Aqurated copper (I) catin undergoes disproportionation as
`2Cu^(+)(aq) rarr Cu^(2+) (aq) + Cu`, because

Assertion: Aquated copper(I) cation undergoes disproportionation as: 2Cu^(+)(aq) to Cu^(2+)(aq)+Cu Reason: Hydration energy of Cu^(2+) is higher than that of Cu^(+) which compensates second ionisation energy of Cu.

Assertion: Aquated copper(I) cation undergoes disproportionation as: 2Cu^(+)(aq) to Cu^(2+)(aq)+Cu Reason: Hydration energy of Cu^(2+) is higher than that of Cu^(+) which compensates second ionisation energy of Cu.

The unique behaviour of CU, having a positive E^(@) (reduction potential) accounts for its inability to liberate H_(2) from acids,. Only oxidising acids (nitric acid and hot concentrated sulphuric acid) react with Cu. The high energy of transform Cu(s) to Cu^(2+)(aq.) is not balanced by its hydration enthalpy. On the other hand, All Cu(II) halides are known except iodide. in this case, Cu^(2+) oxidises I^(-) to I_(2) : 2Cu^(2+)+4I^(-) to 2CuI(s)+I_(2) However, copper (I) compounds are unstable in aqueous solution annd undergo disproportionation. 2Cu^(+)(aq.)toCu^(2+)(aq.)+Cu The stability of Cu^(2+)(aq.) rather than Cu^(+)(aq) is due to the much more negative Delta_(Hyd) of Cu^(2+)(aq.) than Cu^(+)(aq.) Q. Select the correct chemical change:
