Which of the following statements is not true about the complex ion [Pt(en)2Cl2]2+.
  • a)
    It has two geometrical isomers – cis and trans.
  • b)
    Both the cis and trans isomers display optical activity.
  • c)
    Only the cis isomer displays optical activity.
  • d)
    Only the cis isomer has non–superimposable mirror image.
Correct answer is option 'B'. Can you explain this answer?

Explanation:

Statement: Both the cis and trans isomers display optical activity.
- Optical activity is the ability of a molecule to rotate the plane of polarized light.
- In the case of the complex ion [Pt(en)2Cl2]2+, the cis isomer displays optical activity, while the trans isomer does not.
- The reason for this is that the cis isomer has a non-superimposable mirror image, which gives rise to the optical activity.
- The trans isomer, on the other hand, is symmetrical and hence does not exhibit optical activity.
Therefore, statement B ("Both the cis and trans isomers display optical activity") is not true for the complex ion [Pt(en)2Cl2]2+.
