Concept explainers
Expand the list of orbitais considered in Figures 5.2 and 5.3 by using all three p orbitals of atom A and all five d orbitals of atom B. Which of these have the necessary match ofsymmetry for bonding and antibondingorbitals? These combinations are rarely seen in simplemolecules but can be important in transition metal complexes.
Interpretation: The list of orbitals should be expanded using all three p-orbitals of atom A and all five d-orbitals of atom B and the orbitals should be selected which has necessary match of symmetry for bonding and antibonding orbitals.
Concept Introduction: Three conditions are considered for overlapping which leads to bonding.
- The orbital’s symmetry must be such that regions with the same sign of ψ overlap.
- The energies of atomic orbital must be comparable.
- In order to provide good overlap, the distance between the atoms should be short enough but not so short as the repulsion of other electrons or nuclei occur.

- What are the point groups of a tetragonally compressed tetrahedral and square planar geometry of this complex?arrow_forwardUse resonance forms to show that the dipolar sigma complex shown in the sulfonationof benzene has its positive charge delocalized over three carbon atoms and its negativecharge delocalized over three oxygen atoms.arrow_forwardCFT is applicable to molecules in geometries other than octahedral. In octahedral complexes, remember that the lobes of the eg set point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place,but now we have only four ligands located between the axes (as given). None of the orbitals points directly at the tetrahedral ligands. However, the eg set (along the Cartesian axes) overlaps with the ligands less than does the t2g set. By analogy with the octahedral case, predict the energy diagram for the d orbitals in a tetrahedral crystal field. To avoid confusion, the octahedral eg set becomes a tetrahedral e set, and the octahedral t2g set becomes a t2 set.arrow_forward
