Bond order for N2 molecule is __________________?
Correct answer: C. 3
- A. 2
- B. 1
- C. 3
- D. 4
Explanation
In N2, the three shared electron pairs consist of one sigma bond and two pi bonds, so the bond order is 3. Students may choose 2 by counting only the pi bonds, but bond order counts both sigma and pi bonding pairs.

About Sigma and Pi Bonds
A sigma bond forms by direct end-to-end overlap along the internuclear axis, whereas a pi bond forms by sideways overlap of parallel orbitals. The topic covers single, double and triple bonds, bond composition, restricted rotation and the relation between sigma and pi bonding and orbital hybridisation.
