Which outcome occurs when sigma (*) antibonding orbitals dominate?

A)Paramagnetism significantly decreases overall substance
B)Bond length increases between atoms
C)Increased quantum tunnelling probability occurs
D)Resonance stabilisation becomes energetically favoured

💡 Explanation

Antibonding orbitals are higher energy than bonding orbitals; therefore, population of sigma (*) orbitals causes increased bond length due to repulsive electronic interactions, rather than paramagnetism because paired electrons dominate, or tunnelling because nuclear properties matter more.
