Q27 · CSIR-NET Chemistry, June 2017

Paper: CSIR-NET June 2017 · Subject: Inorganic Chemistry · Chapter: Coordination Chemistry · Topic: Coordination Chemistry – General · Marks: 2 · Difficulty: Easy

The relative rates of water exchange for the hydrated complexes of (1) $\mathrm{Ni}^{2+}$ (2) $\mathrm{V}^{2+}$ and (3) $\mathrm{Cr}^{3+}$ ions follows the trend:
(a)$(1)>(2)>(3)$
(b)$(1)<(2)<(3)$
(c)$(1)>(2)<(3)$
(d)$(1)<(2)>(3)$
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
Water exchange: Ni²⁺ (~10⁴ s⁻¹) > V²⁺ (d³, ~10² s⁻¹) > Cr³⁺ (d³, ~10⁻⁶ s⁻¹) — (1) > (2) > (3) (a).
