The electronic configurationo of Cu(II) is `3d^(9)` whereas that of Cu(I) is `3d^(10)`. Which of the following is correct ?A. Cu(II) is more stableB. Cu(II) is less stableC. Cu(I) and Cu(II) are equally stableD. Stability of Cu(I) and Cu(II) depends on nature of copper salts |

Answer» Correct Answer - A Cu(II) is more stable than Cu(I). As it is known that, Cu(I) has `3d^(10)` stable configuration while Cu(II) has `3d^(9)` configuration. But Cu(II) is more stable due to greater effective nuclear charge of Cu(II) i.e., it hold 17 electrons instead of 18 in cu(I). |
