MCQ
Identify the optically active compounds from the following:
- A[Co(en)3]3+
- BTrans– [Co(en)2Cl2]+
- CCis– [Co(en)2Cl2]+
- D[Cr(NH3)5Cl]
✓
Answer
- [Co(en)3]3+
- Cis– [Co(en)2Cl2]+
Explanation:
(a, c) [Co(en)3]3+ and cis [Co(en)2Cl2]2+ are optically active compounds because their mirror images are non-superimposable isomer.
Non-supermposable isomers of [Co(en)3]3+
Non-superimosable isomers of [Co(en)2Cl2]+
Hence, (a) and (c) are correct choices.
