The elements in the oxidation level to below can create octahedral low spin complexes:Hf (II); W (II); OS (VI) b) V (IV); Fe (III); (IV)c) Cr (II); Tc (III); Ru (IV) d) Nb (III); Mn (III); Co (III)Explain (just explain option selected)Electron configuration of Cr (II) has http://iTunes.Apple.com/us/album/you-skinny-Hebrew-live/id352134363?i=352134391&IGN-mpt=UO%3d4, Tc (III) has 4d4, Ru (IV) there should be 4d4 if B > P then octahedral complexes of them in the low-spin state: d4do.Question 17Choose the right sentence: For the complex [Co (NH3) 6] 3 +: = 273.2 kJ/mol, P = 250.5 kJ/molNot yet enough data to conclude about the complexLow spin complex is on complex, DiamagnetismHigh spin complex, the complex agreement fromThe complex is high spin complex, on the DiamagnetismQuestion 18Write the electron configuration of the complexes [CoF6] 3-Crystal field theory and conclude this is high or low spin-spin complex, it is ParaMagnetic complexes known.low spinhigh spinUnable to determinehigh spinQuestion 20. Select the correct statements about the complexes [MnBr4] 2-:1. name: tetrabromomangan Complexes (II).2. This is positive from the complex.3. Complex can have high or low spin configuration.4. high-spin complexes is Complicated by Crystal field theory. a) Only 2, 4 true b) 1, 2, 4 c) 1, 3 true true true 2.3)Verse 18: Select the correct statements about the complexes [MnBr4] 2-, know it is ParaMagnetic complexes:Name: complex tetrabromomanganat (II).The complexes have tetrahedral configuration due to the combination of the orbital 4s and 4 p form 4 hybrid orbital theory sp3theo Covalent chemistry.The complex has a square configuration is due to the combination of the orbital 3d, 4s, and 4 p form 4 hybrid orbital d2sp chemistry.The complex is high spin complex according to the Crystal field theory.1, 2, 4 right1, 3, 4 right1, 3 right1, 2 rightVerse 21: Select the correct statements about the nature of the complex: (1) K2, [Zn (OH) 4], (2) Hg [Co (SCN) 4] (Co2 +)1) K2, [Zn (OH) 4] is the tetrahedral complex, Diamagnetism, Hg [Co (SCN) 4] tetrahedral complexes are ParaMagnetic.2) Hg [Co (SCN) 4] Crystal field stabilization energy more complex sound-K2 [Zn (OH) 4]3) K2, [Zn (OH) 4] and Hg [Co (SCN) 4] is the colorless compound.1, 2 right2, 3 right1, 3 rightThere is no correct answer.Question 22. Select the correct statements about the Cu2 + complexes of Crystal field theory:1 octahedral complexes) of Cu (II) have the electron configuration of the d level 2 different forms complexes with ligand field and the field strength.2) complexes of Cu2 + only 1 unique profile is d6d4.
