Which one of the following is expected to exhibit optical isomerism? (en = ethylenediamine )
Options
- Ac i s- [ Pt ( NH ₃ )₂ Cl ₂ ]
- Btrans- [ Co ( en )₂ Cl ₂ ]
- Ctrans - [ Pt ( NH ₃ )₂ Cl ₂ ]
- Dcis - [ ( Co ( en )₂ Cl ₂ ] .
Correct answer
B. trans- [ Co ( en )₂ Cl ₂ ]
Step-by-step solution
Cis (- [ Co ( en )₂ Cl ₂ ]⁺ ) is able to show the phenomenon of optical isomerism because it can form a superimposable mirror image. It gives super imposable structure but trans-form is optically inactive.
