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

Options

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

Answer

B, D

Explanation

The lattice energy released for `Cu^(2+)` compound is much higher than `Cu^(+)` due to high charge `+2` and smaller size.
