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.

The crystal field theory considers the metal-ligand bond to be which type of bond?

Ionic

The CFT is an electrostatic model which considers the bond between metal ion and the ligand to be ionic arising due to the electrostatic interactions between them.
