The d electron congfiguration of `Cr^(2+)` , `Mn^(2+)` , `Fe^(2+)` and `Ni^(2+)` are `3d^(4)` , `3d^(5)` , `3d^(6)` and `3d^(8)` respectively. Which one of the folowing aqua complexes will exhibit the minimum paramagnetic behaviour ? `(At. No . Cr = 24, Mn = 25, Fe = 26, Ni = 28)`A. `[Fe(H_(2)O)_(6)]^(+2)`B. `[Mn(H_(2)O)_(6)]^(+2)`C. `[Cr(H_(2)O)_(6)]^(+2)`D. `[Ni(H_(2)O)_(6)]^(+2)` |

Answer» Correct Answer - 4 `H_(2)O` is weak field ligands so, the electrons are not paired up. (1) `n = 4 to mu = 4.85 BM` (2) `n=5 to mu = 5.92 BM` (3) `n=4 to mu = 4.85 BM` (4) `n=2 to mu = 2.8 BM` |
