In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.: ... (such as hexane and benzene), low melting solids (such as paraffin wax and naphthalene) or polymers (such as polyethylene and polystyrene). In the fossil fuel industries, hydrocarbon refers to naturally … Zobacz więcej In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and Zobacz więcej The noteworthy feature of saturated hydrocarbons is their inertness. Unsaturated hydrocarbons (alkanes, alkenes and aromatic compounds) react more readily, by means of substitution, addition, polymerization. At higher temperatures … Zobacz więcej Burning hydrocarbons as fuel, which produces carbon dioxide and water, is a major contributor to anthropogenic global warming. Hydrocarbons are introduced into the environment through their extensive use as fuels and chemicals as well as through … Zobacz więcej As defined by the International Union of Pure and Applied Chemistry's nomenclature of organic chemistry, hydrocarbons … Zobacz więcej The predominant use of hydrocarbons is as a combustible fuel source.
