A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen. [1][2][3]: 16–22 Carbon–oxygen bonds are found in many inorganic compounds such as carbon oxides …

碳－氧键 是指 碳 原子和 氧 原子之间形成的 共价键，这是 有机化学 和 生物化学 中最常见的化学键之一。 [1] 氧原子具有6个 价电子，倾向于与碳原子共用两个电子形成化学键，剩下的四个 …

Like any other double bond, a carbon-oxygen double bond is made up of two different parts. One electron pair is found on the line between the two nuclei - this is known as a sigma bond.

一般含有羧酸官能团 (-COOH)的烃类物质在碱性条件下去质子化,也就是解离H+之后写成- COO-,标表示溶液中以阴离子形似存在 -COONa是羧酸根与Na+离子形成的盐, 一般是上述物质脱水后 …
