Match List-I with List-II: LIST-I (Compound/Species) A. SF4 B. BrF3 C. BrO3- D. NH4+ LIST-II (Shape/Geometry) I. Tetrahedral II. Pyramidal III. See saw IV. Bent T-shape Choose the correct answer from the options given below :

1. A-II, B-III, C-I, D-IV
2. A-III, B-IV, C-II, D-I
3. A-II, B-IV, C-III, D-I
4. A-III, B-II, C-IV, D-I

Correct answer: A-III, B-IV, C-II, D-I

Solution

The correct option matches the molecular geometries of the compounds accurately: SF4 has a see-saw shape due to its four bonding pairs and one lone pair, BrF3 has a bent T-shape due to three bonding pairs and two lone pairs, BrO3- has a pyramidal shape with three bonding pairs and one lone pair, and NH4+ is tetrahedral with four bonding pairs and no lone pairs.
