Describe for any two of the following complex ions, the type of hybridisation, shape and magnetic property : (i) [Fe(H_(2)O)_(6)]^(2+) (ii) [Co(NH_(3))_(6)]^(3+) (iii) [NiCl_(4)]^(2-) (At. Nos. Fe = 26, Co = 27, Ni = 28) |

Answer» Solution :(i) `Fe(H_(2)O)_(6)]^(2+)` -outer orbital (high spin) complex-`sp^(3)d^(2)` HYBRIDISATION, octahedral, diamagnetic. (II) `[Co(NH_(3))_(6)]^(3+)` - inner orbital (low spin) complex- `d^(2)sp^(3)` hybridisation, octahedral, diamagnetic. (iii) `[NiCl_(4)]^(2-)-sp^(3)`, (Electrons PAIR up as `NH_(3)` is a strong ligand) TETRAHEDRAL, paramagnetic. |
