Which of the following pair of elements have greater ability to form $p\pi - p\pi$ multiple bonds?
Show Hint
Second period elements form strongest $\pi$ bonds.
Updated On: Apr 24, 2026
- Carbon and Oxygen
- Boron and Aluminium
- Nitrogen and Phosphorus
- Fluorine and Chlorine
- Carbon and Silicon
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
• $p\pi - p\pi$ bonding is effective when orbitals overlap properly
Step 1: Condition
Small atoms → better orbital overlap → strong $\pi$ bonds
Step 2: Compare
Carbon and Oxygen → small size → strong $\pi$ bonding
Others involve larger atoms → poor overlap Final Conclusion:
