Which of the following is not a biofuel?

Question

BlackTom AI · Accepted Answer

Let’s evaluate each option in terms of what qualifies as a biofuel. 
Option a: ethene. Ethene is a simple hydrocarbon used primarily as a chemical feedstock for polymers (like polyethylene) and is not produced from biological sources as a fuel. It is not considered a biofuel. 
Option b: Ethanol. Ethanol is a classic biofuel obtained from fermentation of sugars in crops such as sugarcane or corn, and is widely used as a renewable transportation fuel. This fits the definition of a biofuel. 
Option c: Methyl esters of fatty acids. These are biodiesel components produced from fats or oils via transesterification, and they are explicitly used as a renewable biofuel for diesel engines. This is a biofuel. 
Option d: Biogas. Biogas consists mainly of methane and carbon dioxide produced by anaerobic digestion of organic matter; it can be burned for energy and is considered a biofuel. 
In summary, the statement that does not describe a biofuel is option a, ethene, since it is not derived from biological materials for fuel use, unlike ethanol, methyl esters of fatty acids (biodiesel), and biogas.
