pal, although Cu+ has a very stable conf.(stable core) but cu2+ is more stable... it is because everytime there mest be a balnce bet. nuclear charge and outer e syst... as in cu nuclear charge is not suff. enough to hold outer 18 e (cu+ conf) togethr it givs one more e to become a more stable core.....cu2+

well,i am not exactly sure if my ans is correct,bt cu2+ has a much stabler existence in aq solution due to the fact that it has a very highly negative enthalpy of hydration....
in aq medium,thus cu+ disproportionates to cu and cu2+ as then the cu2+ gets hydrated and the enthalpy of the net reaction is negative enough,hence favouring the entire reaction...
the Enought value for reduction of cu2+ to cu+ is also highly negative for the same reason....
