Hydrocarbon A compound of carbon and hydrogen

A sample of a hydrocarbon (a compound of carbon and hydrogen only) is burned, and 2.20 g CO, and 0.900g H20 are produced. What is the empirical formula of the hydrocarbon ... 

AROMATIC HYDROCARBON A compound of carbon and hydrogen with a molecular structure based on that of benzene. 

Hydrocarbon A compound of carbon and hydrogen only. Hydrocarbons may have linear, branched or cychc structures, and may be saturated or unsaturated. 

We can extend this idea to experiments involving combustion data of hydrocarbons. The example below shows how the formula of propane and the stoichiometry of the equation can be deduced. Propane is a hydrocarbon - a compound of carbon and hydrogen only. 

A combustion reaction involves the reaction of a substance with oxygen gas. The complete combustion of any hydrocarbon (binary compound of carbon and hydrogen) produces carbon dioxide and water as the only products. Octane is a hydrocarbon found in gasoline. Complete combustion of octane produces 8 L of carbon dioxide for every 9 L of water vapor (both measured at the same temperature and pressure). What is the ratio of carbon atoms to hydrogen atoms in a molecule of octane ... 

Dulong used, without stating it explicitly, what was later called Dulong s rule , that the heat of combustion of a compound of carbon and hydrogen is the sum of the heats of combustion of the carbon and hydrogen it contains. This implies that the heat of formation of a hydrocarbon is zero it was disproved by Favre and Silbermann, although it is nearly true for ethylene. They found that addition of C H ==4vols. [sic] decreased the heat of combustion of a hydrocarbon by 37-48 cal. Thomsen determined the heats of com-...

Aromatic Hydrocarbon n (1) A compound of carbon and hydrogen whose molecular structure contains one or more rings of six carbon atoms, with at least one of the rings containing alternating, resonant single and double bonds. Benzene, which is the simplest of the aromatic hydrocarbons, has the molecular formula CeHe. The family includes many solvents for plastics. 

A compound of carbon and hydrogen contains 85.7% carbon and 14.3% hydrogen by mass. Deduce the empirical formula of this hydrocarbon, values C = 12.0,0 = 16.0)... 

Hydrocarbons, compounds of carbon and hydrogen, are stmcturally classified as aromatic and aliphatic the latter includes alkanes (paraffins), alkenes (olefins), alkynes (acetylenes), and cycloparaffins. An example of a low molecular weight paraffin is methane [74-82-8], of an olefin, ethylene [74-85-1], of a cycloparaffin, cyclopentane [287-92-3], and of an aromatic, benzene [71-43-2]. Cmde petroleum oils [8002-05-9], which span a range of molecular weights of these compounds, excluding the very reactive olefins, have been classified according to their content as paraffinic, cycloparaffinic (naphthenic), or aromatic. The hydrocarbon class of terpenes is not discussed here. Terpenes, such as turpentine [8006-64-2] are found widely distributed in plants, and consist of repeating isoprene [78-79-5] units (see Isoprene Terpenoids). 

Alkanes, alkenes, alkynes, and aromatic compounds are members of a family of organic compounds called hydrocarbons, compounds of carbon and hydrogen. These hydrocarbons are the simplest of organic compounds, but are extremely important to our society as fuels and raw materials for chemical industries. We... 

Terpenes are a large and diverse class of compounds produced by a wide variety of organisms, though plants are an especially prolific source. The terms terpenoid and isoprenoid can be used interchangeably with terpene, though, strictly, terpenes are hydrocarbons (composed only of carbon and hydrogen) while terpenoids and iso-prenoids have been further functionalized. 

Gasoline is a mixture of hydrocarbons, that is compounds of carbon and hydrogen, of which hexane C6Hi4, heptane C7Hi6, and octane CgHu, are the principal ones. Gasoline and carbon disulphide are very combustible. Carbon tetrachloride and chloroform do not bum. 

The structures and nomenclature of organic chemistry are all based on the carbon and hydrogen skeleton, known as a hydrocarbon. Different arrangements of carbon and hydrogen atoms, as well as the addition of other atoms or groups of atoms, allow a wide diversity in the number and types of organic compounds. In this chapter, we will proceed from the most basic hydrocarbons to more complex arrangements. 

Carbon has by far the greatest number of compounds of any element. The thousands of combinations of carbon with other elements give it the diversity of compounds that makes it the basis of life. Carbon has a reacting power of 4 as it has four electrons in its outermost shell and is placed in group 4 of the periodic table. Its chemical bonds are all covalent. There are over half a million compounds of carbon and hydrogen alone and some are very useful, including the hydrocarbons in petrol. 

Hydrocarbon. A binary compound of carbon and hydrogen a general term which includes the paraffin, olefin, aromatic, and all other series of hydrides of carbon. 

Although crude petroleum contains small amounts of oxygen, nitrogen, and sulfur, its major constituents are hydrocarbons—compounds of carbon and hydrogen. Isolating individual hydrocarbon substances from petroleum mixtures is an industrial process of central importance. Moreover, it provides a fascinating story that illustrates how the structures of molecules determines the properties of substances and the behavior of those substances in particular processes. The next three sections present a brief introduction to this story, emphasizing the structure-property correlations. 

Crude oil is the naturally occurring liquid which is a mixture of compounds of carbon and hydrogen. The proportions of the hydrocarbons vary significantly. Some of them occur as gases, others as solids, and both are in solution in liquid hydrocarbons. Since crude oil is a mixture, it does not have a fixed chemical composition or physical properties. The composition of crude oils ranges from 83 to 86% carbon, and from 11 to 14% hydrogen. 

In this chapter, I give you a brief introduction to organic chemistry. I spend some time showing you the hydrocarbons, compounds of carbon and hydrogen, as well as some other classes of organic compounds and their uses in everyday life. As you read this chapter, you ll find that a lot of chemistry can be found in carbon. 

In a catalytic cracking plant ( cat crackers, as they re called in Texas), fractions in the C12 to C20 range are heated in the absence of air with a catalyst. This process causes the long alkanes (compounds of carbon and hydrogen with only carbon-to-carbon single bonds, which are covered in glorious detail in Chapter 14) to break apart into smaller alkanes and alkenes (hydrocarbons with at least one carbon-to-carbon double bond, covered in equally glorious detail in Chapter 14). 

Natural gas is primarily methane, CH4. Petroleum is a mixture of hydrocarbons (compounds of carbon and hydrogen). Liquefied petroleum gas (LPG) is a mixture of propane (CsHs) and butane (C4H10).
