MCQ
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.
The complex $\left[ Cr ( ox )_3\right]^3$ contains no symmetry element and is chiral. It can be resolved into $d$ and $l$ form.
The complexes cis $-\left[ PtCl _2( en )\right]$, cis $-\left[ RhCl _2\left( NH _3\right)_4\right]^{+}$andmer $-\left[ Co \left( NO _2\right)_3(\right.$ dien $\left.)\right]$ contain symmetry elements and are achiral.
