Petroleum based fuels are?

Explanation:
Petroleum-based fuels are hydrocarbons, molecules made only of hydrogen and carbon. Refined from crude oil, fuels like gasoline and diesel are mixtures of many hydrocarbon chains, from light to heavy. These fuels store energy in C–H bonds and release it during combustion. Alcohols contain oxygen and a hydroxyl group, esters are derived from acids and alcohols (often found in biodiesel contexts), and ketones include a carbonyl group; none of these chemistries represent the typical composition of traditional petroleum fuels. So hydrocarbons best describe petroleum-based fuels.
