Different theories have been put forward to explain the geometrical of co-ordianation compounds. Out of them , the most practical is the valence bond theory which is based upon the concept of hybridisation . According to this , the complexes with C.N.4 may be either tetrahedral (sp^(3) hybridised ) or square planar (dsp^(2) hybridised ) in nature. Similarly , in the octahedral complexes , the metal atom or ion is either paramagnetic if one or more orbitals are half-filled and diamagnetic if all are filled in nature. 5. Which is correct in the case ofcomplex ?
