Question:

Case: Read the passage and answer the following questions

Crystal field theory (CFT) describes the breaking of degeneracies of electron orbital states, usually d or f orbitals, due to a static electric field produced by a surrounding charge distribution (anion neighbours). This theory has been used to describe various spectroscopies of transition metal coordination complexes, in particular optical spectra (colours). CFT successfully accounts for some magnetic properties, colours, hydration enthalpies, and spinel structures of transition metal complexes, but it does not attempt to describe bonding.

Which of the following ligands will be treated as point dipoles in CFT?

Options:

NO2

CN

Cl

NO

Correct Answer:

NO

Explanation:

Anionic ligands are treated as point charges and neutral ligands are treated as point dipoles in crystal field theory.
