Diagram of Ethene (C₂H₄):

[Image missing: Ethene Structure]

The bonding in ethene is primarily covalent. Each carbon atom shares two electrons with the other carbon atom, forming a double bond. The presence of the double bond makes ethene unsaturated. This is because the double bond means that ethene has fewer hydrogen atoms than a saturated hydrocarbon with the same number of carbon atoms. It can undergo addition reactions to form saturated hydrocarbons.
