the bonding electrons are π electrons, which is at variance with the notion that single bonds are always σ bonds. 成键电子是电子,这与单键总是键的看法不一致。

Instead some of the double - bond electrons become delocalized , shared among several atoms rather than localized in a specific bond between two atoms 有些双键里的电子四处游移,由许多原子所共有,而非停留在两个原子间的特定一根键上。
