Question

Discuss molecular orbital diagram for H2 and O2 calculate bond order

Answer 1

bond order of H2 is 1 nd for O2 is 2

Answer 2

The atom of hydrogen gas is the most unstable atom which reserves its existence at only high temperature. To make stable, the hydrogen atom combines with other hydrogen atom. According to Valence Bond Theory, to form a chemical bond, their orbitals overlap.

Bond order is 1/2.

Molecular orbital of O2 suggests that it is paramagnetic because it has two unpaired electrons. The orbitals overlap to form the sigma and pi orbital.

Bond order is 2.
