Which of the following complexes exhibits the highest paramagnetic behaviour? where gly=glycine, en=ethylenediamine and bipy =bipyridyl (At. no. `Ti=22, V=23, Fe=26, Co=27`)A. (a) `[Ti(NH_3)_6]^(3+)`B. (b) `[Fe(en)(bpy)(NH_3)_2]^(2+)`C. (c) `[Co(OX)_2(OH)_2]^(-)`D. (d) `[V(gly)_2(OH)_2(NH_3)_2]^(+)` |

Answer» Correct Answer - A `Fe^(2+)`, `Co^(5+)`, `Ti^(3+)` and `V^(3+)` have 4, 4, 1, 2 unpaired electrons respectively. The pairing leads `Fe^(2+)` with no unpaired electron. |
