Cupric compounds are more stable than their cuprous counter parts in solid state. This is because :
(WB JEE 2014)
\( P \)
(a) the endothermic characteristics of the 2 nd IP of \( \mathrm{Cu} \) is not so high
(b) size of \( \mathrm{Cu}^{2+} \) is less than \( \mathrm{Cu}^{+} \)
W.
(c) \( \mathrm{Cu}^{2+} \) has stable electronic configuration as compared to \( \mathrm{Cu}^{2+} \)
(d) the lattice energy released for cupric compounds is much higher than \( \mathrm{Cu}^{+} \)
