Question

Cuprous compounds such as $CuCl, CuCN$ and $CuSCN$ are the only salts stable in $H_2O$ due to

A

high hydration energy of $Cu^+$ ions

B

their inherent tendency not to disproportionate

C

diamagnetic nature

D

insolubility in water

Answer

high hydration energy of $Cu^+$ ions

Explanation
