Question

Match List I with List II

List-I (Compound)		List-II (Shape/geometry)
(A)	NH3	(I)	Trigonal Pyramidal
(B)	BrF5	(II)	Square Planar
(C)	XeF4	(III)	Octahedral
(D)	SF6	(IV)	Square Pyramidal

Choose the correct answer from the options given below:

• A. A-I, B-IV, C-II, D-III
• B. A-II, B-IV, C-III, D-I
• C. A-III, B-IV, C-I, D-II
• D. A-II, B-III, C-IV, D-I

Answer 1

The Correct Option is A

Step 1: Analyze Compound Geometries

• A. \( NH_3 \) (Ammonia):
  • Structure: Trigonal pyramidal.
  • Central atom: Nitrogen, bonded to three hydrogen atoms and possessing one lone pair.
• B. \( BrF_5 \) (Bromine Pentafluoride):
  • Geometry: Square pyramidal.
  • Central atom: Bromine, bonded to five fluorine atoms and possessing one lone pair.
• C. \( XeF_4 \) (Xenon Tetrafluoride):
  • Geometry: Square planar.
  • Central atom: Xenon, bonded to four fluorine atoms and possessing two lone pairs.
• D. \( SF_6 \) (Sulfur Hexafluoride):
  • Geometry: Octahedral.
  • Central atom: Sulfur, surrounded by six fluorine atoms.

Step 2: Match Compounds to Geometries

• A-I: \( NH_3 \) corresponds to trigonal pyramidal geometry.
• B-IV: \( BrF_5 \) corresponds to square pyramidal geometry.
• C-II: \( XeF_4 \) corresponds to square planar geometry.
• D-III: \( SF_6 \) corresponds to octahedral geometry.

Step 3: Conclusion

The established matches are:

A-I, B-IV, C-II, D-III
