Among the following complexes, (i) $\left[\mathrm{Ru}(\text { bipyridyl })_{3}\right]^{+}$ (ii) $[\mathrm{Cr}(\mathrm{EDTA})]^{-}$ (iii) trans- $\left[\mathrm{CrCl}_{2} \text { (oxalate) }{ }_{2}\right]^{3-}$ (iv) cis- $\left[\mathrm{CrCl}_{2} \text { (oxalate) }{ }_{2}\right]^{3-}$ the ones that show chirality are
(a)(i), (ii), (iv)
(b)(i), (ii), (iii)
(c)(ii), (iii), (iv)
(d)(i), (iii), (iv)
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
[Ru(bpy)₃]⁺ (Δ/Λ), [Cr(EDTA)]⁻ (hexadentate wrap) and cis-[CrCl₂(ox)₂]³⁻ are chiral; the trans isomer has a mirror plane — (i), (ii), (iv) (a).
