Select CORRECT code for π -bond in given molecule :- Column-I (Molecule) Column-II (If one atom use it's 'np' orbital for π - bond formation then type of orbital used for p bond formation by other atom) (P) SOF 4 ​ (1) n p (Q) CS 3 ​ 2 − (2) ( n + 1 ) p (R) CO (3) (n + 1) d (S) BrO 3 ​ − (4) (n + 2) d Code: (P) (Q) (R) (S)

TestHub · Accepted Answer

(P) SOF₄

S forms π bond with O using 3d orbitals (expanded octet)
O uses 2p → S uses (n+1)d

(Q) CS₃²⁻

C uses 2p, S (3rd period) can use 3p orbitals for π bonding
overlap is pπ–pπ, so other atom uses np but here due to charge delocalization

(R) CO

Both C and O use 2p orbitals → pure pπ–pπ overlap

(S) BrO₃⁻

Br (4th period) forms π bond using d orbitals
O uses 2p → Br uses (n+1)d or higher
