Question

Given below are two statements: 
Statement I: A homoleptic octahedral complex, formed using monodentate ligands, will not show stereoisomerism 
Statement II: cis- and trans-platin are heteroleptic complexes of Pd. 
In the light of the above statements, choose the correct answer from the options given below

• A. Both Statement I and Statement II are false
• B. Statement I is true but Statement II is false
• C. Statement I is false but Statement II is true
• D. Both Statement I and Statement II are true

Hint:

- Homoleptic complexes have only one type of ligand - Geometrical isomerism requires different spatial arrangements - Cis/trans-platin are classic examples of geometrical (not optical) isomerism - Platinum (Pt) complexes \(\neq\) Palladium (Pd) complexes

Answer 1

The Correct Option is B

Analysis of Statement I:
- A homoleptic octahedral complex with monodentate ligands (e.g., \([Co(NH_3)_6]^{3+})\) has identical ligands in all positions - No geometrical or optical isomers possible as all positions are equivalent - Therefore, Statement I is true
Analysis of Statement II:
- cis-platin and trans-platin are actually Pt(II) complexes, not Pd - Both are homoleptic complexes (contain same ligands: \([PtCl_2(NH_3)_2])\) - The difference is in ligand arrangement (cis/trans), not heteroleptic nature - Therefore, Statement II is false
