Chemistry · Chemical Bonding and Molecular Structure
The bond order and bond strength in molecular nitrogen (N2) are higher than in molecular oxygen (O2) primarily due to which of the following reasons?
- 1O2 has a larger atomic radius, reducing overlap efficiency.
- 2N2 has a triple bond sharing six electrons, leading to higher bond order than the double bond in O2.✓
- 3The π-bonding in O2 weakens its bond strength.
- 4The unpaired electrons in O2 increase repulsion and weaken bonding.
Correct answer
N2 has a triple bond sharing six electrons, leading to higher bond order than the double bond in O2.
