Using valence bond theory (VBT), account for the geometry, type of hybridization and magnetic property of [NiCl_(4)]^(2-). |
Answer» Solution :The oxidation state of nickel inP `[NiCl_(4)]^(2+)` is+2. The outer electronic configuration of nickel(+2) is `3d^(8)4S^(0)`-  When weak ligand, Cl“ is approaching towards central METAL ION, one 4s and three 4p orbitals hybridised to yield four `sp_(3)` hybrid orbitals pointing towards the four comers of tetrahedron  Each Cl- ion donates a pair of ELECTRONS to four `sp_(3)` hybrid orbitals to form tetrahedral complex. Due to the presence of two of unpaired electrons, the compound is PARAMAGNETIC in nature. Conclusions:- 1/Hybridisation- `Sp_(3)` 2. Geometrical shape – tetrahedral 3. Magnetic property - Paramagnetic. |
