Question

Match List-I with List-II:

List-I	List-II
(A) XeF2	(iii) Linear
(B) BF3	(i) Trigonal Planar
(C) XeF4	(ii) Distorted Octahedral
(D) SF6	(iv) Regular Octahedral

Choose the correct answer from the options given below:

• (A) - (i), (B) - (iii), (C) - (ii), (D) - (iv).
• (A) - (iii), (B) - (i), (C) - (ii), (D) - (iv).
• (A) - (iv), (B) - (iii), (C) - (ii), (D) - (i).
• (A) - (iii), (B) - (iv), (C) - (i), (D) - (ii).

Hint:

VSEPR theory is used to determine molecular geometries by minimizing electron pair repulsions. Lone pairs are more repulsive than bonding pairs and therefore tend to compress bond angles, distorting the geometry from its ideal shape.

Answer 1

The Correct Option is B

Based on VSEPR theory, the molecular geometries are:
• \(XeF_2\): Linear, attributed to three lone pairs and two bond pairs.
• \(BF_3\): Trigonal planar, attributed to three bond pairs and no lone pairs.
• \(XeF_4\): Distorted octahedral, featuring four bond pairs and two lone pairs.
• \(SF_6\): Regular octahedral, featuring six bond pairs and no lone pairs.
The corresponding correct matches are: (A) - (iii), (B) - (i), (C) - (ii), (D) - (iv).
