The bond order of H2+ is.
Correct answer: A. 1/2
- A. 1/2
- B. 1
- C. 2
- D. 1.5
Explanation
The bond order of H2+ is 1/2. This means that the molecule has a half-filled bonding orbital. The bond order is calculated by taking the difference between the number of bonding electrons and the number of anti-bonding electrons and dividing it by 2. In the case of H2+, there is only one bonding electron and no anti-bonding electrons, resulting in a bond order of 1/2.

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.
