Cuprous compounds such as CuCI, CuCN and CuSCN are the only salts stable in water due toA. high hydration energy of `Cu^(+)` ionsB. their inherent tendency not to disproportionateC. diamagnetic natureD. insolubility in water |

Answer» Correct Answer - D Cuprous compounds are those in which copper is monovalent. Most of the cuprous compounds are colourless and dimagnetic as 3d- subhell is completely filled. However, `Cu_(2)O` and `Cu_(2)S` are and black respectively. Cuprous compounds are generally insoluble in water. The soluble compounds are unstable in aqueous solutions, since they disproportionate to `Cu^(2+)` and Cu. `2Cu^(+) rarr Cu^(2+) + Cu` |
