← ScienceWhich outcome results when the molecular orbitals of butadiene misalign?
A)Loss of conjugated system stability✓
B)Increased rotational energy barrier
C)Greater electron delocalization overall
D)Decreased HOMO-LUMO energy gap
💡 Explanation
Loss of stability occurs in Butadiene due to incorrect orbital alignment because π electrons cannot delocalize along the chain; the mechanism is orbital overlap. Therefore, conjugated stability is reduced rather than leading to other effects which require maintained overlap.
