Question 35

Bond order normally gives idea of stability of a molecular species. All the molecules viz. $$H_2$$, $$Li_2$$ and $$B_2$$ have the same bond order yet they are not equally stable. Their stability order is :

$$H_2$$ is the most stable because it has the smallest atomic size and zero destabilizing antibonding electrons.

$$B_2$$ is more stable than $$Li_2$$ because Boron's smaller atomic radius yields a shorter, stronger bond.
