Chemistry - Coordination Chemistry Question with Solution | TestHub
Select pair which have same magnetic nature & same kind of isomerism.
Options:(select one or more)
Answer:
Solution:
The question asks to select pairs with the same magnetic nature and the same kind of isomerism.
Let's analyze each option:
Option A:
1. : Square planar, Pt(II) is d⁸, diamagnetic. Exhibits geometrical isomerism (cis/trans).
2. : Square planar, Pt(II) is d⁸, diamagnetic. Exhibits geometrical isomerism (cis/trans).
Both are diamagnetic and show geometrical isomerism.
Option B:
1. : . Fe(II) is d⁶. CN⁻ is a strong field ligand, so it's low spin, diamagnetic.
2. : . Ni(II) is d⁸. NO₂⁻ is a strong field ligand, so it's low spin, diamagnetic.
Both are diamagnetic. Both are octahedral complexes and can exhibit linkage isomerism (due to NO₂⁻) and optical isomerism if chiral. However, the question asks for the same kind of isomerism. Both are octahedral and can exhibit optical isomerism if chiral.
Option C:
1. : . Co(III) is d⁶. en is a strong field ligand, so it's low spin, diamagnetic. This complex is chiral and exhibits optical isomerism.
2. : . Co(III) is d⁶. C₂O₄²⁻ is a strong field ligand, so it's low spin, diamagnetic. This complex is chiral and exhibits optical isomerism.
Both are diamagnetic and exhibit optical isomerism.
Option D:
1. : . Pt(II) is d⁸, square planar, diamagnetic. Exhibits ionization isomerism with .
2. : . Co(III) is d⁶. NH₃ is a strong field ligand, so it's low spin, diamagnetic. Exhibits ionization isomerism with .
Both are diamagnetic and exhibit ionization isomerism.
Therefore, options B, C, and D are correct.
The final answer is .
