LIST-I contains metal species and LIST-II contains their properties.
| LIST-I | LIST-II |
|---|---|
| (I) \( [\mathrm{Cr}(\mathrm{CN})_6]^{4-} \) | (P) \( t_{2g} \) orbitals contain \( 4 \) electrons |
| (II) \( [\mathrm{RuCl}_6]^{2-} \) | (Q) \( \mu (\text{spin-only}) = 4.9\,\mathrm{BM} \) |
| (III) \( [\mathrm{Cr}(\mathrm{H_2O})_6]^{2+} \) | (R) low spin complex ion |
| (IV) \( [\mathrm{Fe}(\mathrm{H_2O})_6]^{2+} \) | (S) metal ion in \( 4+ \) oxidation state |
| (T) \( d^4 \) species |
[Given: Atomic number of \( \mathrm{Cr} = 24 \), \( \mathrm{Ru} = 44 \), \( \mathrm{Fe} = 26 \)]
Match each metal species in LIST-I with their properties in LIST-II, and choose the correct option:
