Weboctahedral complex with weak field ligands whereas it forms diamagnetic octahedral complex with strong field ligands. 29. Why are low spin tetrahedral complexes not formed? 30. Give the electronic configuration of the following complexes on the basis of Crystal Field Splitting theory. [CoF 6]3–, [Fe(CN) 6]4– and [Cu(NH 3) 6]2+. 31. Explain ... WebThe degenerate d-orbitals (in a spherical field environment) split into two levels i.e., eg and t2g in the presence of ligands. The splitting of the degenerate levels due to the presence of ligands is called the crystal-field splitting while the energy difference between the two levels (eg and t2g) is called the crystal-field splitting energy. It is denoted by ∆o. Fig. d …

Web(iii) Crystal field splitting in an octahedral field. Answer: Question 59: Write the structures and names of all the stereoisomers of the following compounds: (i) [Co (en) 3]Cl 3 (ii) [Pt(NH 3) 2 Cl 2] (iii) [Fe(NH 3) 4 Cl 2] … WebThe splitting of the degenerate levels due to the presence of ligands is called the crystal-field splitting while the energy difference between the two levels (e g and t 2g) is called … WebCrystal field splitting by various ligands. Metal complexes show different colours due to d-d transitions. The complex absorbs light of specific wavelength to promote the electron from t 2 g to eg level. The colour of the complex is due to the transmitted light, which is complementary of the colour absorbed. michelle muldrow obgyn
