Which outcome occurs when a triatomic molecule's delocalized π-system exceeds overlap limits?

A)Increased non-bonding electron probability
B)Molecular orbital phase cancellation
C)Decreased vibrational energy coupling
D)Enhanced singlet-triplet intersystem crossing

💡 Explanation

Molecular orbital phase cancellation destabilizes the bonding because destructive interference reduces electron density between atoms via ANTI-BONDING. The molecule can then dissociate or bend, rather than maintain its structure, therefore reducing the electronic stabilization of linear structures.
