Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(P) CO: Contains a triple bond consisting of one $\sigma$ and two $\pi$ bonds, including a coordinate bond ($C\leftarrow O$), matching (3).

(Q) XeO₃: Has sp³ hybridization with one lone pair, resulting in a pyramidal geometry, matching (1).

(R) ClF₃: Its sp³d hybridization leads to a T-shaped structure where all four atoms lie in the same plane, matching (2).

(S) SO₂Cl₂: Has sp³ hybridization with different terminal atoms, creating an imperfect tetrahedral geometry, matching (4).

Conclusion: The correct sequence is $P\to 3,Q\to 1,R\to 2,S\to 4$, which corresponds to Option (B).
