Question

Match the LIST-I with LIST-II.

Choose the correct answer from the options given below :

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

Hint:

In molecular structures, use the VSEPR theory to determine the number of bonding and lone pairs on the central atom, which helps in predicting the molecular geometry and bond pair to lone pair ratios.

Answer 1

The Correct Option is B

Let's analyze the molecular structures: ICl\(^-\): This ion has a central iodine atom with 2 bonding pairs and 3 lone pairs, resulting in a 2 : 3 ratio (option III). H\(_2\)O: 
The oxygen atom has 2 lone pairs and 2 bonding pairs, which gives the ratio 2 : 2 (option IV). SO\(_2\): 
The sulfur atom has 2 bonding pairs and 1 lone pair, leading to a 4 : 1 ratio (option II). 
XeF\(_4\): The xenon atom has 4 bonding pairs and 2 lone pairs, giving the ratio 4 : 2 (option I).
Therefore, the correct matching is: A-III, B-IV, C-II, D-I.
