Conditions for formation of the delocalized π-bond in ABn molecules were discussed in detail. Three steps were introduced to help judging the formation of delocalized π-bond in ABn molecules. The delocalized π-bond in some non-planar molecules was also discussed.

Key words: Delocalized π-bond, Valence shell electron pair repulsion, Hybridized orbital
