WebAlkenes have a carbon-carbon double bond and alkynes have a carbon–carbon triple bond. Nomenclature rules are given in Sec. 3. Each carbon of a double bond is trigonal, and connected to only three other atoms, all of which lie in a plane with bond angles of 120o. Ordinarily, rotation around double bonds is restricted.
