Discussion of the Delocalized π-Bond in AB_n Molecules

College of Chemistry and Molecular Sciences, Wuhan University, Wuhan 430072, P. R. China

Conditions for formation of the delocalized π-bond in AB_n molecules were discussed in detail. Three steps were introduced to help judging the formation of delocalized π-bond in AB_n molecules. The delocalized π-bond in some non-planar molecules was also discussed.
- Delocalized π-bond,
- Valence shell electron pair repulsion,
- Hybridized orbital
