`Cu^(+)` ion is not stable in aqueous solution because because of dispropotionation reaction. `E^(@)` value of disproportionation of `Cu^(+)` is `[E_(Cu^(2+)//Cu^(+))^(@)=+ 0.15 V, E_(Cu^(2+)//Cu)^(@)=0.34 V]`A. second ionisation entyhalpy of copper is less than the first ionisation enthalpyB. large value of second ionisation enthalpy of copper is compensated by much more negative hydration energy of `Cu_((aq))^(2+)`C. hydration energy of `Cu_((aq))^(2+)` is much more negative than that of `Cu_((aq))^(2+)`D. many copper (I) compounds are unstable in aqueous solution and undergo disproportionation rection. |
