Which one of the following complexes exhibit chirality?
- ✓$[Cr(ox)_3]^3$
- Bcis $-[PtCl_2(en)]$
- Ccis $-[RhCl(NH_3)_4]^+$
- Dmer $-[Co(NO_2)_3(dien)]$
✓
Answer
Correct option: A.
$[Cr(ox)_3]^3$
a
The complex $\left[ Cr ( ox )_3\right]^3$ contains no symmetry element and is chiral. It can be resolved into $d$ and $l$ form.
