Ethane vs. Ethene: What's the Difference?
Ethane (C₂H₆) is a saturated hydrocarbon with single bonds, while ethene (C₂H₄), also known as ethylene, is an unsaturated hydrocarbon with a double bond between carbon atoms.
Ethane and ethene are both hydrocarbons, compounds made up of only carbon and hydrogen atoms. Ethane, having the chemical formula C₂H₆, is an alkane. Alkanes are saturated hydrocarbons, meaning they only possess single bonds between the carbon atoms. Being saturated ensures that ethane has the maximum possible number of hydrogen atoms for its two carbon atoms.
On the contrary, ethene, with the chemical formula C₂H₄, belongs to the alkene family. Alkenes are unsaturated hydrocarbons characterized by the presence of at least one double bond between carbon atoms. This double bond results in ethene having two fewer hydrogen atoms compared to ethane, even though they both contain two carbon atoms.
From a usage perspective, ethane is predominantly employed as a feedstock in the production of ethene. This transformation happens through a process called cracking. Ethene, on the other hand, is a critical compound in the petrochemical industry, primarily used for producing polyethylene, a common plastic.
Ethane's single-bonded structure makes it relatively unreactive. Conversely, the double bond in ethene provides an area of higher electron density, making it more reactive than ethane. This reactivity is why ethene readily participates in addition reactions, such as polymerization.
When discussing sources, ethane is commonly extracted from natural gas and is a significant component of many natural gas deposits. Ethene, while it can be directly sourced in minor quantities, is primarily produced industrially from hydrocarbons like ethane through the aforementioned cracking process.
