Copper (I) compounds are white and diamagnetic while copper (II) compounds are coloured and paramagnetic and form coloured compounds.Explain. |
| Answer» Solution :In Copper (I) ION, all orbitals are completely filled `(1s^(2) 2S^(2) 2p^(6) 3s^(2) 3p^(6) 3s^(10))` and, therefore, it is diamagnetic and forms white compounds. Copper (II) ion has electronic CONFIGURATION. `(1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3s^(9))` ( has ONE unpaired electron) and , therefore,it is PARAMAGNETIC and forms coloured compounds. | |
