The compound [Co(H2O)6]2+, having three unpaired electrons, shows the ...
From Quantum Mechanics viewpoint, the magnetic moment is dependent on both spin and orbital angular momentum contributions. The spin-only formula used is given by
And this can be modified to include the orbital angular momentum as follows.
Therefore, the value of the magnetic moment can differ because of the contribution of the total orbital motion of the electron to the magnetic moment. Thus, this is the correct answer.

The compound [Co(H2O)6]2+, having three unpaired electrons, shows the ...
Explanation:
Contribution of orbital motion to magnetic moment:
- The discrepancy between the experimental and theoretical magnetic moments of [Co(H2O)6]2+ can be attributed to the contribution of the orbital motion of the electrons to the magnetic moment.
- The theoretical calculated value only considers the spin magnetic moment of the unpaired electrons but does not take into account the orbital motion contribution.
Effect of orbital motion on magnetic moment:
- The orbital motion of an electron around the nucleus generates an orbital magnetic moment.
- This orbital magnetic moment interacts with the external magnetic field and contributes to the overall magnetic moment of the complex.
- In the case of [Co(H2O)6]2+, the presence of three unpaired electrons with orbital motion contributes to the experimental magnetic moment exceeding the theoretical value.
Reason for discrepancy:
- The discrepancy arises because the theoretical calculation typically focuses only on the spin magnetic moment of the unpaired electrons, neglecting the contribution from orbital motion.
- When the orbital motion contribution is considered, the overall magnetic moment of the complex increases, leading to the observed deviation between the experimental and theoretical values.
Conclusion:
- In summary, the discrepancy in the magnetic moment of [Co(H2O)6]2+ can be explained by the contribution of the orbital motion of the electrons to the magnetic moment, which is not accounted for in the theoretical calculation.
