List I (Molecule):
(A) BrF5
(B) H2O
(C) ClF3
(D) SF4
List II (Shape):
(I) T-shape
(II) See-saw
(III) Bent
(IV) Square pyramidal
Correct Matching: (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
BrF5: AX5E system → square pyramidal shape.
H2O: AX2E2 system → bent shape.
ClF3: AX3E2 system → T-shaped geometry.
SF4: AX4E system → see-saw shape.
Hence, the correct matching is:
(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
