Read the passage given below and answer the following questions:
The crystal field theory (CFT) is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interactions between the metal ion and the ligand. Ligands are treated as point charges in case of anions or dipoles in case of neutral molecules. The five d orbitals in an isolated gaseous metal atom/ion have same energy, i.e., they are degenerate. This degeneracy is maintained if a spherically symmetrical field of negative charges surrounds the metal atom/ ion. However, when this negative field is due to ligands (either anions or the negative ends of dipolar molecules like NH3 and H2O) in a complex, it becomes asymmetrical and the degeneracy of the d orbitals is lifted. It results in splitting of the d orbitals.
The following questions are multiple choice questions. Choose the most appropriate answer:
Q. The colour of the coordination compounds depends on the crystal field splitting. What will be the correct order of absorption of wavelength of light in the visible region, for the complexes, [Co(NH3)6]3+, [Co(CN)6]3−, [Co(H2O)6]3+
  • a)

Explanation:

Crystal Field Splitting:
- The crystal field splitting refers to the energy difference between the d orbitals in a transition metal complex.
- The magnitude of this splitting determines the color of the complex.

Order of Absorption of Wavelength of Light:
- The order of absorption of wavelength of light in the visible region is determined by the crystal field splitting in the complexes.
- In the given options, [Co(H2O)6]3+ has the highest crystal field splitting, followed by [Co(NH3)6]3+ and then [Co(CN)6]3−.

Explanation of Correct Answer (Option C):
- [Co(H2O)6]3+ has the highest crystal field splitting among the three complexes.
- Therefore, it will absorb light of shorter wavelengths in the visible region, resulting in a yellow color.
- [Co(NH3)6]3+ has intermediate crystal field splitting, absorbing light of longer wavelengths in the visible region, resulting in a violet color.
- [Co(CN)6]3− has the lowest crystal field splitting, absorbing light of the longest wavelengths in the visible region, resulting in a red color.

Conclusion:
- The correct order of absorption of wavelength of light in the visible region for the complexes is [Co(H2O)6]3+ > [Co(NH3)6]3+ > [Co(CN)6]3−.
