उत्तर
The pair having the same magnetic moment is `bbunderline([Cr(H_2O)_6]^(2+) and [Fe(H_2O)_6]^(2+))`.
Explanation:
- [Cr(H2O)6]2+: Cr2+ has a d4 configuration, leading to 4 unpaired electrons.
- [Fe(H2O)6]2+: Fe2+ has a d6 configuration and also results in 4 unpaired electrons in a high-spin octahedral complex.
Thus, both complexes have the same number of unpaired electrons (4), so their magnetic moments are the same, approximately 4.9 BM.
