(a) What type of isomerism is shown by the complex [Co(NH_(3))_(5)(SCN)]^(2+) ? (b) Why is [NiCl_(4)]^(2-) paramagnetic while [Ni(CN)_(4)]^(2-) is diamagnetic ? (Atomic no. of Ni = 28) (c ) Why are low spin tetrahedral complexes rarely observed ? |
| Answer» SOLUTION :(a) Linkage isomerism, (c ) They involve `SP^(3)` HYBRIDISATION. The 3d orbitals do not participate in hybridisation. | |
