FAQs on Splitting Of D Orbital Energies In Fields Of Other Symmetry (Tetragonal & Square Planar) Video Lecture - Inorganic Chemistry

1. What is the splitting of d orbital energies in tetragonal fields?
Ans. In tetragonal fields, the d orbital energies split into two sets, namely eg (e g symmetric) and t2g (t 2g symmetric) orbitals. The eg orbitals have higher energy and are located along the tetragonal axis, while the t2g orbitals have lower energy and are located in the xy plane perpendicular to the axis.
2. How does the splitting of d orbital energies occur in square planar fields?
Ans. In square planar fields, the d orbital energies split into two sets, namely eg (e g symmetric) and t2g (t 2g symmetric) orbitals, similar to the tetragonal field. However, in square planar complexes, the splitting of the d orbitals is more pronounced, resulting in larger energy differences between the eg and t2g sets.
3. What causes the splitting of d orbital energies in different symmetry fields?
Ans. The splitting of d orbital energies in different symmetry fields is caused by the crystal field theory. When a transition metal ion is surrounded by ligands, the ligands generate a crystal field that affects the energies of the d orbitals. The electrostatic interactions between the metal ion and the ligands result in the splitting of the d orbital energies.
4. How does the splitting of d orbital energies affect the properties of transition metal complexes?
Ans. The splitting of d orbital energies affects the properties of transition metal complexes in various ways. It influences the absorption and emission spectra, magnetic properties, and reactivity of the complexes. The energy difference between the split d orbitals determines the color of the complex, while the number of unpaired electrons in the higher-energy orbitals affects its magnetic behavior.
5. Can the splitting of d orbital energies be experimentally observed?
Ans. Yes, the splitting of d orbital energies can be experimentally observed through spectroscopic techniques, such as UV-Vis spectroscopy and magnetic susceptibility measurements. These techniques allow researchers to study the absorption and emission of light by transition metal complexes and determine the energy differences between the split d orbitals.
