Cupric compounds are more stable than their cuprous counterparts in solid state. This is because -

Options

A. the endothermic character of the `2^(nd)` IP of Cu is not so high
B. size of `Cu^(2+)` is less than that of `Cu^(+)`
C. `Cu^(2+)` has stable electronic configuration as compared to `Cu^(+)`
D. the lattice energy released for cupric compounds is much higher than `Cu^(+)`

Answer

D

Explanation

With the increase in the charge, the lattice energy of the solid increases. Again with the increase of the lattice energy, stability of the solid increases.
