Question

Out of bonding and antibonding which is filled first and why

Answer 1

Placing an electron in the bondingorbital stabilizes the molecule because it is in between the two nuclei. Conversely, placing electrons into the antibonding orbitals will decrease the stability of the molecule. ... They will first fill the lower energy orbitals, and then they will fill the higher energy orbitals......


pls follow me

Answer 2

bonding because it has lower energy
