Question

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 π 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

SOF₄

S central atom (period 3) → can use 3d orbital → (n+1)d = 4d for p-bonding

CS₃²⁻

C = period 2 → only uses 2p orbital → (n+1)p = 3p for p-bond

CO

C and O → both period 2 → use 2p orbital → np

BrO₃⁻

Br = period 4 → can use 4d orbital → (n+2)d = 6d
