Application of VB theory for the specific complexQuestion 62: Choose the correct variant:The complexes [CoF6] 3-ParaMagnetic. According to the VB theory [CoF6] 3-isOctahedral high spin complex, Co3 + chemical sp3d2 hybrid.Octahedral low-spin complex, Co3 + hybrid d2sp3 chemistry.Octahedral low-spin complex, Co3 + chemical sp3d2 hybrid.Octahedral high spin complex, Co3 + hybrid d2sp3 chemistry.64. Select correct variant:The complex [Co (NH3) 6] 3 + is Diamagnetism. According to the theory of Covalent structure of the complexes, which are:CO3 + hybrid d2sp3 chemistry in the inner orbital complex creationCO3-chemical sp3d2 hybrid status + in creating internal orbital complexCO3 + hybrid culture in d2sp3 forms complexes orbital foreignCO3-chemical sp3d2 hybrid status + in creating complex orbital foreign63. Select correct variant:The complexes [NiCl4] 2-(1) is ParaMagnetic with two electrons, the complex [Ni (CN) 4] 2-(2) is Diamagnetism. According to the theory, Covalent structure of 2 complexes that are:(1) Ni2 + in future chemical state sp3, (2) Ni2 + in dsp2 chemistry hybrid status(1) Ni2 + in dsp2 chemistry hybrid status, (2) Ni2 + in future chemical state sp3Ni2 + in future chemical state sp3 in both complexesNi2 + in dsp2 chemistry hybrid status in both complexes65. Choose correct:The complexes [NiCl4] 2-is ParaMagnetic. According to the theory of Covalent structure of the complexes, which are:Ni2 + in the hybrid status of the chemical complex creation tetrahedral sp3Ni2 + in the hybrid status turned flat square forms complexes with sp3Ni2 + in dsp2 chemistry hybrid status created tetrahedral complexesNi2 + in dsp2 chemistry hybrid status created square Planar complexes
