Understanding Optical Isomerism
Optical isomerism occurs when a compound can exist in two non-superimposable mirror images, known as enantiomers. This phenomenon is generally observed in chiral molecules, which lack an internal plane of symmetry.
Analysis of the Given Compounds
Let's evaluate the compounds provided:
Correct Answer: [Cr(CO)6]
The correct answer is option 'C': [Cr(CO)6'.
In summary, only the compound [Cr(CO)6 can exhibit optical isomerism due to its ability to form chiral arrangements.
Optical isomerism occurs when a compound can exist in two non-superimposable mirror images, known as enantiomers. This phenomenon is generally observed in chiral molecules, which lack an internal plane of symmetry.
Analysis of the Given Compounds
Let's evaluate the compounds provided:
- [ZnCl]2: Zinc has a d10 configuration and typically forms tetrahedral complexes. It does not exhibit optical isomerism as it does not possess chirality.
- [Cu(NH3)]2: This complex can form square planar or tetrahedral geometries. However, with ammonia as a ligand, it does not present any chiral centers leading to optical isomerism.
- [Cr(CO)6: The chromium complex with CO is octahedral and symmetrical. All substituents are equivalent, so it cannot exhibit optical isomerism.
- [Co(CN)3: This cobalt complex is octahedral and can have chiral configurations depending on the ligands' arrangement. However, the given compound has a symmetrical arrangement and does not show optical isomerism.
Correct Answer: [Cr(CO)6]
The correct answer is option 'C': [Cr(CO)6'.
- In this case, chromium can form different geometrical isomers depending on the ligand arrangement.
- The presence of carbon monoxide as a ligand allows for the formation of chiral complexes, leading to optical isomerism.
- These isomers can rotate plane-polarized light in different directions, confirming their chiral nature.
In summary, only the compound [Cr(CO)6 can exhibit optical isomerism due to its ability to form chiral arrangements.
