Which of the following does not show optical isomerism? [2009]a)[Co(NH...
Explanation:
Optical isomerism: Optical isomerism is a form of stereoisomerism that occurs when a molecule is non-superimposable on its mirror image. This occurs when there is a chiral center in the molecule, which is a carbon atom bonded to four different groups.
Chiral center: A chiral center is a carbon atom that is bonded to four different groups. It is also known as an asymmetric carbon atom.
Analysis of the given complexes:
a) [Co(NH3)3Cl3]0
- In this complex, the central cobalt (Co) atom is bonded to four different groups: three ammonia (NH3) molecules and one chloride (Cl) ion.
- Therefore, it has a chiral center and can show optical isomerism.
b) [Co (en) Cl2 (NH3)2]
- In this complex, the central cobalt (Co) atom is bonded to four different groups: two ethylenediamine (en) molecules, two ammonia (NH3) molecules, and two chloride (Cl) ions.
- Therefore, it has a chiral center and can show optical isomerism.
c) [Co (en)3]3
- In this complex, the central cobalt (Co) atom is bonded to only one type of ligand, which is ethylenediamine (en).
- Since it does not have a chiral center (carbon atom bonded to four different groups), it cannot show optical isomerism.
d) [Co (en)2Cl2]
- In this complex, the central cobalt (Co) atom is bonded to four different groups: two ethylenediamine (en) molecules and two chloride (Cl) ions.
- Therefore, it has a chiral center and can show optical isomerism.
Conclusion:
The complex that does not show optical isomerism is [Co (en)3]3 (option c) because it does not have a chiral center.
