Question

In which of the molecules lone pair, bond pair of electrons ratio is 2:3 ?

• A. Cl\(_2\)
• B. O\(_2\)
• C. HCl
• D. N\(_2\)

Hint:

Drawing the Lewis structure is essential for this type of question. Remember to count bonding pairs based on the bond order: a single bond is 1 pair, a double bond is 2 pairs, and a triple bond is 3 pairs.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
Find molecule with LP:BP ratio = 2:3.

Step 2: Key Concept (Alternate):
Draw Lewis structures. Count lone pairs and bonding pairs (single=1BP, double=2BP, triple=3BP).

Step 3: Detailed Explanation:
Cl₂: 6LP,1BP(6:1). O₂: 4LP,2BP(2:1). HCl: 3LP,1BP(3:1). N₂: 2LP,3BP(2:3). N₂ matches.

Step 4: Final Answer:
N₂ has LP:BP = 2:3.
