An organic compound that contains only hydrogen and carbon In vehicle emissions, these are usually vapors created from incomplete combustion or from vaporization of liquid gasoline Emissions of hydrocarbons contribute to ground level ozone
(HC) An organic chemical compound consisting only of carbon and hydrogen atoms in the gaseous, liquid or solid phase (Greek hydor, water + Latin, carbo, charcoal)
any of a vast number of compounds containing carbon and hydrogen in various combinations; found especially in fossil fuels Some of the hydrocarbon compounds are major air pollutants; they may be active participants in the photochemical process or affect health
An organic chemical compound of hydrogen and carbon in either the gaseous, liquid, or solid phase The molecular structure of hydrocarbon compounds varies from the simplest (e g , methane, a constituent of natural gas) to the very heavy and very complex
An organic chemical compound of hydrogen and carbon, called petroleum The molecular structure of hydrocarbon compounds varies from the simplet, methane (CH4), a constituent of natural gas, to the very heavy and very complex Octane, for example, a constituent of crude oil, is one of the heavier, more complex molecules
An organic compound of hydrogen and carbon, called petroleum The molecular structure of the hydrocarbon varies from the simplest, methane (CH4, a constituent of natural gas, to the very heavy and very complex Octane, a constituent of crude oil, is one of the heavier, more complex molecules (C8H18)
A hydrocarbon is a chemical compound that is a mixture of hydrogen and carbon. a chemical compound that consists of hydrogen and carbon, such as coal or gas. Any of a class of organic compounds composed only of carbon and hydrogen. The carbon atoms form the framework, and the hydrogen atoms attach to them. Hydrocarbons, the principal constituents of petroleum and natural gas, serve as fuels, lubricants, and raw materials for production of plastics, fibres, rubbers, solvents, explosives, and industrial chemicals. All burn to carbon dioxide and water with enough oxygen or to carbon monoxide without it. The two major categories are aliphatic, with the carbon atoms in straight or branched chains or in nonaromatic rings, and aromatic (see aromatic compound). Aliphatic compounds may be saturated (paraffins) or, if any carbon atoms are joined by double or triple bonds, unsaturated (e.g., olefins, alkenes, alkynes). All but the simplest hydrocarbons have isomers (see isomerism). Ethylene, methane, acetylene, benzene, toluene, and naphthalene are hydrocarbons
An organic compound containing only carbon and hydrogen Large, heavy hydrocarbons may have up to 90 carbon atoms per molecule while small, light hydrocarbons may have only one to four carbon atoms per molecule Different types and sizes of hydrocarbon molecules make up crude oil and natural gas
