Question

Match LIST-I with LIST-II:

	LIST-I (Molecule)		LIST-II (Shape)
A.	$SO_4^{2-}$	I.	Trigonal pyramidal
B.	$ICl_3$	II.	Square planar
C.	$NF_3$	III.	Tetrahedral
D.	$XeF_4$	IV.	Bent T-shaped

Choose the correct answer from the options given below:

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

Answer 1

Answer: (D)

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

Answer 2

Solution:

1. $SO_4^{2-}$: Has 4 bonding pairs and no lone pairs → Tetrahedral geometry → Option III.
2. $ICl_3$: Iodine has 5 electron groups (3 bonds + 2 lone pairs) → T-shaped molecular geometry → Option IV ("Bent T-shaped").
3. $NF_3$: 4 electron groups (3 bonds + 1 lone pair) → Trigonal pyramidal → Option I.
4. $XeF_4$: 6 electron groups (4 bonds + 2 lone pairs arranged opposite) → Square planar → Option II.

Thus, the matching is: A-III, B-IV, C-I, D-II.
