QuestionVSEPR / shapes
Match List-I with List-II and select the correct answer using the code given below the lists:
| List-I (Molecule/ion) | List-II (Shape) |
|---|---|
| A. H₂O | 1. Linear |
| B. BF₃ | 2. Angular |
| C. I₃⁻ | 3. Trigonal planar |
| D. SF₄ | 4. See-saw |
Code:
- (a) A-4, B-1, C-3, D-2
- (b) A-2, B-3, C-1, D-4
- (c) A-2, B-1, C-3, D-4
- (d) A-4, B-3, C-1, D-2
Answer: (b) A-2, B-3, C-1, D-4
A. H₂O: 2 bp + 2 lp → angular (2). B. BF₃: 3 bp → trigonal planar (3). C. I₃⁻: 2 bp + 3 lp → linear (1). D. SF₄: 4 bp + 1 lp → see-saw (4). Code 2-3-1-4 → (b).
