Among N₂, O₂, F₂ and Ne₂, the molecule with the highest bond order is:
AN₂
BO₂
CF₂
DNe₂
Answer & Solution
Correct answer: A. N₂
1. MO bond orders: N₂ = 3, O₂ = 2, F₂ = 1, Ne₂ = 0.
2. N₂ has the highest bond order (triple bond), so the shortest and strongest bond.
3. Ne₂ doesn't exist as a molecule (BO = 0).
