The site contains complex chlorinated and hydrocarbon compounds as well as metals like chrome.
The process was dirty and contaminated the soil with complex hydrocarbon compounds.
All the ants have hydrocarbon compounds on their hard exteriors that other ants can detect with their antennas.
Attached to the ends of the rings are various hydrocarbon compounds, including normal paraffin chains.
Kerogen, complex waxy mixture of hydrocarbon compounds that is the primary organic component of oil shale.
Oil consists of a closely related series of complex hydrocarbon compounds that range from gasoline to heavy solids.
Kerogen is a complex waxy mixture of hydrocarbon compounds composed of algal remains or of amorphous organic matter with varying amounts of identifiable organic remnants.
Naphthalene, the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms; chemical formula, C10H8.
In addition to the practically infinite mixtures of hydrocarbon compounds that form crude oil, sulfur, nitrogen, and oxygen are usually present in small but often important quantities.
Because they consist of mixtures of thousands of hydrocarbon compounds, their physical properties such as colour, specific gravity, and viscosity also vary widely.
The oxygen content of crude oil is usually less than 2 percent by weight and is present as part of the heavier hydrocarbon compounds in most cases.
