Designate the following complexes X, Y and Z as inert or labile: $\mathrm{X = [Al(C_2O_4)_3]^{3-}},\ \mathrm{Y = [V(H_2O)_6]^{2+}},\ \mathrm{Z = [Cr(C_2O_4)_3]^{3-}}$
(a)X and Y are inert; Z is labile
(b)X and Z are labile; Y is inert.
(c)X is inert; Y and Z are labile
(d)X is labile; Y and Z are inert.
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
[Al(C₂O₄)₃]³⁻ (d⁰, no CFSE) is labile; [V(H₂O)₆]²⁺ and [Cr(C₂O₄)₃]³⁻ are d³ (t₂g³, large CFSE) and are inert (d).
