High and low field ligands
WebOverview of crystal field theory. According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged metal cation and the negative charge on the non-bonding electrons of the ligand. The theory is developed by considering energy changes of the five degenerate d-orbitals upon being … WebCyanide ion is a strong ligand. It will cause greater splitting between the respective orbitals. In case of strong ligands, pairing of electrons will be higher. Therefore, they are low-spin complexes. Therefore, strong field ligands such as cyanide produce low spin complexes and high field splitting. Therefore, the correct option is (c).

The … WebStrong-field ligands, such as CN − and CO, increase the Δ splitting and are more likely to be low-spin. Weak-field ligands, such as I − and Br − cause a smaller Δ splitting and are more likely to be high-spin. Some octahedral complexes exhibit spin crossover, where the high and low spin states exist is dynamic equilibrium.
