Worked practice questions

In valence bond theory, hybrid orbitals are:

  1. real orbitals seen in spectra
  2. orbitals from the ligands only
  3. a mathematical construct
  4. orbitals of free metal atoms
Show answer and solution

Correct answer: C. a mathematical construct

Hybrid orbitals do not physically exist; they come from mathematically combining atomic orbital wave functions.

In crystal field theory, how is a neutral ligand such as NH₃ treated?

  1. As a point charge
  2. As a pi acceptor
  3. As a covalent donor
  4. As a point dipole
Show answer and solution

Correct answer: D. As a point dipole

Anionic ligands are modelled as point charges, while neutral molecules are modelled as point dipoles.

In an octahedral crystal field, which d orbitals are raised in energy?

  1. dxz and dyz
  2. dx²-y² and dz²
  3. dxy, dyz and dxz
  4. dxy and dz²
Show answer and solution

Correct answer: B. dx²-y² and dz²

The dx²-y² and dz² orbitals point along the axes straight at the ligands, so they feel more repulsion and form the eg set.
