Hydrocarbons are organic compounds composed exclusively of hydrogen and carbon atoms, forming the backbone of petroleum, natural gas, and many industrial chemicals. They are classified into several categories based on their molecular structure, including alkanes, alkenes, alkynes, and aromatic hydrocarbons. Alkanes are saturated hydrocarbons with single bonds, such as methane (CH₄) and ethane (C₂H₆), while alkenes and alkynes contain double and triple bonds, respectively, making them unsaturated. Aromatic hydrocarbons, like benzene (C₆H₆), feature ring structures with delocalized electrons, contributing to their unique stability and reactivity.

Hydrocarbons serve as critical energy sources, with fossil fuels like gasoline, diesel, and propane being derived from crude oil and natural gas. They are also essential feedstocks in the petrochemical industry, where they undergo processes like cracking, reforming, and polymerization to produce plastics, synthetic rubber, solvents, and other synthetic materials. The versatility of hydrocarbons stems from their ability to undergo various chemical reactions, including combustion, substitution, and addition reactions.

Environmental concerns surround hydrocarbons due to their role in air pollution, greenhouse gas emissions, and oil spills. Combustion of hydrocarbons releases carbon dioxide (CO₂) and other pollutants, contributing to climate change and smog formation. Efforts to mitigate these impacts include the development of cleaner fuels, such as biofuels and hydrogen, as well as advancements in carbon capture technologies. Additionally, hydrocarbons are increasingly being explored for sustainable applications, such as biodegradable plastics and renewable energy sources derived from algae and other biological sources.
