| List I (Compound/Species) | List II (Shape/Geometry) |
|---|---|
| A. SF4 | III. See-saw |
| B. BrF3 | IV. Bent T-Shape |
| C. BrO3− | II. Pyramidal |
| D. NH4+ | I. Tetrahedral |
Correct Answer: A-III, B-IV, C-II, D-I
SF4 has AX4E type geometry → see-saw shape.
BrF3 has AX3E2 type → T-shaped (bent T-shape).
BrO3− has three bond pairs and one lone pair → pyramidal.
NH4+ has four bond pairs and no lone pair → tetrahedral.
