Arrange following complex ions in increasing order of crystal field splitting energy (DO) : [Cr(Cl)6]3–, [Cr(CN)6]3–, [Cr(NH3)6]3+.

Question

Philoid · Accepted Answer

The increasing order of crystal field energy is

[Cr(Cl)₆]^3–<[Cr(NH₃)₆]³⁺ <[Cr(CN)₆]^3–

This is also the order of field strength of the ligands according to the spectrochemical series. A ligand with higher field strength will split the degenerate d orbitals more than a ligand with lower field strength.

Arrange following complex ions in increasing order of crystal field splittingenergy (DO) :[Cr(Cl)6]3–, [Cr(CN)6]3–, [Cr(NH3)6]3+.
