Epoxyethane

Epoxyethane is simuler to ethene, with the exception that it does not have a double bond. Instead, the double bond has been saturated such that each carbon atom now bonds to the same oxygen atom. The formula is C₂H₄O, and can be shown like so:

CH₂ - CH₂

  |   |
 Oxygen

Each carbon atom is bonded with the central oxygen, and so the oxygen has two bonds with each carbon atom.
