Question

What is the value of bond order in H₂ molecuel?

Answer 1

Formula for Bond order = 1/2

(No. Of e- in bonding MO -  

No. Of e- in antibonding MO).

For H2, bond order = 1/2 (2-0) = 1, which means H2 has only one bond.

The anti-bonding orbital is empty.

Thus, H2 is a stable molecule.

It is easy to understand with correct formula.
