Question:
Which of the following shows correct order of bond length?
Which of the following shows correct order of bond length?
Show Hint
Higher bond order ⟹ shorter bond length.
Updated On: Mar 19, 2026
- O₂⁺ > O₂ > O₂⁻ > O₂²-
- O₂⁺ < O₂ < O₂⁻ < O₂²-
- O₂⁺ < O₂⁻ < O₂ < O₂²-
- O₂⁺ > O₂ < O₂⁻ > O₂²-
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Bond order decreases as electrons are added to antibonding orbitals.
Bond order:
O₂⁺ (2.5) > O₂ (2) > O₂⁻ (1.5) > O₂²- (1)
Step 2: Bond length is inversely proportional to bond order.
⟹ Shortest → Longest
O₂⁺ < O₂ < O₂⁻ < O₂²-
