Which items are examples of hydrocarbon materials that may be encountered?

• A. Water, Sand, Wood
• B. Biofuels (gas), Adhesives, Pesticides
• C. Grass, Leaves, Soil
• D. Concrete, Steel, Plastic

Answer: (B)

Hydrocarbon materials are substances made mainly of carbon and hydrogen. On a site you’re likely to encounter several examples, including fuels (gasoline and other biofuels), adhesives that rely on petroleum-based hydrocarbon polymers, and many pesticides built on hydrocarbon frameworks. Water and sand aren’t hydrocarbons. Wood and other plant matter contain oxygen in their structure, so they’re not hydrocarbons either. Concrete and steel are inorganic materials, not hydrocarbons. Plastics are hydrocarbons, but when a choice mixes plastics with non-hydrocarbons, it doesn’t represent hydrocarbon materials as clearly as the option that lists biofuels, adhesives, and pesticides. So that trio best illustrates hydrocarbon-based materials you might encounter.
