In water, oxygen's 8 electrons are arranged with 2 in each sp3 hybridized orbital.

在水中， 氧的 8 个电子在每个 sp3 杂化轨道中排列 2 个。

As they come together for the bond, the sigma bonds will occur between the hybridized orbitals.

当它们聚在一起形成键时， σ键将出现在杂化轨道之间。

The carbon is going to have 2 double bonds, so it has to have 2 un-hybridized p orbitals and one sp hybridized orbital.

碳将具有 2 个双键，因此它必须具有 2 个未杂化的 p 轨道和一个 sp 杂化轨道。

It only hybridizes 2 p orbitals with the s orbital, forming 3 sp2 hybridized orbitals with an unhybridized p orbital sticking up from the center.

它仅将 2 个 p 轨道与 s 轨道杂化， 形成 3 个 sp2 杂化轨道，其中未杂化的 p 轨道从中心伸出。
