Match ALL applicable properties. Use ideal CFT and orbital CFSE without pairing energy. gly⁻ is an unsymmetrical N,O-chelate. Which complete code is correct?
List-I | List-II |
|---|---|
[P] [Fe(CN)₆]⁴⁻ | [1] Diamagnetic |
[Q] [Cr(H₂O)₆]³⁺ | [2] Has an enantiomeric pair |
[R] tetrahedral [Be(gly)₂] | [3] Orbital CFSE = −2.4Δₒ |
[S] low-spin [Rh(en)₃]³⁺ | [4] Three unpaired electrons |
Options:
Answer:
A
Solution:
P is paired ⁶ with −2.4Δₒ and no optical pair. Q is d³ with three unpaired electrons. R is d⁰, diamagnetic and chiral as a tetrahedral bis-unsymmetrical-chelate. S is paired d⁶ with the Δ/Λ tris-chelate pair, matching 1,2,3.
