| List-I (Molecule) | List-II (Shape) |
|---|---|
| (A) \(NH_3\) | (I) Square pyramid |
| (B) \(BrF_5\) | (II) Tetrahedral |
| (C) \(PCL_5\) | (III) Trigonal pyramidal |
| (D) \(CH_4\) | (IV) Trigonal bipyramidal |
To solve this question, we need to determine the correct shape for each molecule listed in List-I based on their molecular geometry, and then match them with the options in List-II. We will assess each molecule's electron pair and bond pair geometries:
Matching these descriptions with List-II, we get:
The correct answer is: A-III, B-I, C-IV, D-II.
NH$_3$: Trigonalpyramidal ({sp}$^3$ hybridization with one lone pair on N).
BrF$_5$: Squarepyramidal ({sp}$^3${d}$^2$ hybridization with one lone pair on Br).
PCl$_5$: Trigonalbipyramidal ({sp}$^3${d} hybridization, no lone pairs).
CH$_4$: Tetrahedral ({sp}$^3$ hybridization, no lone pairs).
Matching: A-III, B-I, C-IV, D-II.
Final Answer: A-III, B-I, C-IV, D-II.
