Correct answer: C
- Identify the hybridisation of each central atom/ion
We match each species in LIST-I with the correct hybridisation in LIST-II.
- For
- Central atom:
- Number of bond pairs around P = 5
- Geometry: trigonal bipyramidal
- Hybridisation:
So,
- For
- Central atom:
- Number of bond pairs around S = 6
- Geometry: octahedral
- Hybridisation:
So,
- For
- Nickel is in oxidation state
- Electronic configuration of :
- In , due to strong field ligand CO, electrons pair up to give effective arrangement suitable for tetrahedral complex.
- Known hybridisation of is
So,
- For
- Oxidation state of Pt:
- So Pt is
- is a system
- For 5d metal , complexes are typically square planar
- Square planar hybridisation is
So,
- Final matching
Thus we get:
This corresponds to Option C.
- Comparison with stored answer
Stored correct answer = C
Our derived answer = C
So they agree.
