alkanes are hydrocarbons with single covalent bonds between the carbon atoms, while alkenes are hydrocarbons with one or more double covalent bonds between the carbon atoms. hydrocarbons are either aliphatic or aromatic. alkanes and alkenes are aliphatic hydrocarbons, which means they are both formed when oils or fats are degraded chemically.read more≫
