Question

Why sigma bond has less energy then sigma star (molecular orbital theory)?

Answer 1

Answer:

This orbital is called sigma-star(σ*) and is less stable than the two separated atoms. Because it is less stable than the two individual atoms, it is called an anti-bonding molecular orbital. ... One is called the highest occupied molecular orbital (HOMO), because it is the highest energy orbital holding electrons.
