← ScienceWhich consequence results when antibonding molecular orbitals are solely occupied during the formation of dilithium?
A)Increased bond order occurs overall
B)No sigma or pi bonds form
C)Dihelium becomes thermodynamically stable
D)Li₂ non-existence will be favoured✓
💡 Explanation
The occupation of only antibonding orbitals activates destabilization because bond order decreases due to destructive interference; therefore Li₂ non-existence should be favored, rather than promoting stable bonding because stabilization requires filled bonding orbitals.
