Question

Explain about the molecular orbital diagram of hydrogen molecule.

Answer 1

1. Electronic configuration of H atom 1s¹

2. Electronic configuration of H, molecule – σ1s¹ Bond order

Bond order = \(\frac{N_b-N_a}{2}\) = \(\frac{2-0}{2}\) = 1

3. Molecule (H₂) has no unpaired electrons, hence it is diamagnetic.
