Question

Match List I with List II 

Choose the correct answer from the options given below:

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

Answer 1

The Correct Option is D

To match List I (molecules/ions) with List II (number of lone pairs of electrons on the central atom), we need to understand the molecular geometry and electron distribution of each molecule/ion. Here is the step-by-step explanation: 

1. IF₇: Iodine has 7 fluorine atoms attached, with no lone pairs. It forms a pentagonal bipyramidal structure. Number of lone pairs = 0.
2. ICl₄^-: The iodine has 4 chlorine atoms attached and 2 lone pairs. The structure is square planar. Number of lone pairs = 2.
3. XeF₆: Xenon is surrounded by 6 fluorine atoms and has 1 lone pair, forming a distorted octahedral shape. Number of lone pairs = 1.
4. XeF₂: Xenon has 2 fluorine atoms and 3 lone pairs, resulting in a linear shape. Number of lone pairs = 3.

Based on the above reasoning, the correct match is:

List I (molecules/ions)	List II (No. of lone pairs of e- on central atom)
(A) IF7	IV. Zero
(B) ICl4-	III. Two
(C) XeF6	II. One
(D) XeF2	I. Three

The correct answer is: A - IV, B - III, C - II, D - I.
