Isopropane.\n\n"The number of hydrogen atoms associated with a given skeleton of carbon atoms may vary.  When the chain or ring carries the full complement of hydrogen atoms, the hydrocarbon is said to be "saturated".  Such hydrocarbons are known as paraffins, paraffinic hydrocarbons, or alkanes/cycloalkanes. The "paraffin" term was common in the oil industry, because of the waxy characteristics of crude which contains these molecules.  The term "alkanes" is common among chemists.\n\nStraight-chain  structures are "normal paraffins", branch-chain structures are "isoparaffins", and ring-type structures are "cycloparaffins" or naphthenes.  Thus for three hydrocarbons with five carbon atoms (i.e. all "pentanes") we have several structures."

C6H14\nAll alkanes follow the same formula:\nC(n)H(2n+2) where n is any real number.\nSo hexane, hex meaning 6, is 6 carbons, and 12+2 hydrogens, 14.

Gotta love wiki\n\nhttp://en.wikipedia.org/wiki/Octane\n\nclick on each one of the 18 isomers, then you can draw. Basically, you shift a methyl group from carbon 1 on down the line so you don't have a straight hydrocarbon chain.

Crude oils vary in their composition, but generally range around 20% gasoline and naphtha, 35% gas oil, 20% lube distillate, 20% residuum, and 5% light gasoline. Refinery processes turn low quality material into higher quality products. \n\nPlastic manufacturers use processes like refiners, or purchase products to produce the chemicals that are used in synthesizing plastics. Since crude oil contains many molecules, the industry breaks and builds molecules to fill the niche. I'll discuss just a portion of the most notable processes. \n\nFluid Catalytic Cracking breaks larger molecules into Gases, Gasoline, Gas oil, and Heavy bottoms. The product streams produced by the FCC contain unsaturated hydrocarbons referred to as olefins. The gases are separated and stored, sold, or used in subsequent processes. \n\nOf these gases produced, propene is used in the manufacture of cumene. For information regarding Cumene, see this website. There's a lot of information. http://www.aristechchem.com/products/cumene.htm \n\nThe other processes that are important are the reforming and alkylation processes. Reforming converts naphthenes into aromatics like benzene, toluene, xylenes, and alkylbenzenes. These chemicals have their roles in the plastics industry. If you visited the above websites, benzene and propene are the feeds for producing cumene. \n\nAlkylation builds larger molecules from smaller molecules. Typically, butenes are mixed with iso-butanes to produce branched chain hydorcarbon polymers called isoparaffins. \n\nIn the United States alone, production of polymers as long ago as 1981 was more than 24 million metric tons, exceeding in volume the production of steel, and is the basis for industries that employs more than 3.5 million people. So, what are polymers? \n\nPolymers are simply very large molecules (macromolecules) that are made up of smaller molecules (monomers) that can be linked together in various ways, resulting in a range of what we call microstructures (e.g., linear chains, branched chains, densely interconnected networks, and so on). Although natural polymers (cotton, wool, silk), have been used throughout recorded history, the first true synthetic polymers were produced relatively recently (in historical terms), at the start of the 20th century. Furthermore, the long chain nature of their chemical structure was not recognized until the 1920s. In the decades that followed, however, an astonishing range of new synthetic materials were quickly produced by polymer chemists, revolutionizing some older industries, like those based on rubber, paint, and natural fibers, and creating new ones associated with the production of plastic goods. Polymers are also a crucial component of other advanced technologies, such as those essential to the electronics industry, where polymers are an integral part of the chip and printed circuit production process. \n\nClearly, there is a broad range of industries that are based on polymer science and engineering. There are two categories of companies. The first consists of those chemical companies that actually make the resins; poly (ethylene), poly(propylene), poly(styrene), PVC, polyesters, nylons, etc. This part of the industry is dominated by large multinational companies with familiar names; Dupont, Dow, Union Carbide, Bayer, Exxon Mobil, Shell, etc. Most of the materials they now produce can be considered commodities and are sold to companies that constitute the second part of the industry, those firms that process polymers into films, fibers, paints, adhesives, composites (e.g., glass fiber reinforced polyesters) and the extraordinary range of plastic goods that are in modern society. The "chemical" part of the industry has from its inception been on the cutting edge of synthetic and chemical processing technology. Even today, it is still introducing new ways to make "old" polymers through the use of novel catalysts (e.g., metallocenes), which promise superior

Luken is right.\n\n\nThe answer is 20.

All alkanes exist as two or more isomers is not true\n\nbecause methane, ethane and propane are also alkane, but they have no isomers.

It formed of dead bodies of plankton million years ago, found in certain rock formation called reservoir. Produced by drilling an oil well and gathered into surface facilities. Separated from its impurities (sediments and water), it transported mostly by pipeline to the refineries. The refineries extract the crude components at each weights to make various type of fuel such as gasoline, kerosene, diesel oil and so on. Crude oil composed by carbons and hydrogen that so called hydrocarbon. Hydrocarbons constitute a very large group including alkanes, alkenes, and alykynes.\nIt's non-renewable energy resources.

Its a mixture of hydrocarbons. It doesn not have a name because it is not composed of one compound.

Most of the info provided is superfluous.\nSimply put, you burned something and got 4.161g H2O (MW=18.016), all H coming from the sample.\nSo you formed 4.161/18.016 = 0.23096 mols H2O, and since each mol H2O contains 2 mols H, your sample contained 0.4619 mols of H.\n\nBTW, it is easy to deduce the empirical formula of the compound:\nNo hydrocarbon can have a MW of 60.095, and since only CO2 and H2O were formed, the compound  must contain O...this works out to be C3H8O, which means it is probably propanol (n or iso) or methyl ethyl ether.

2C8H18 + 2502 ---> 16CO2 + 18H20\nit sometimes helps to first solve H then C then O in that order.

Methane is a very easily made hydrocarbon.  With abundant carbon and hydrogen in space, and plenty of solar radiation, the reaction is not difficult.  Many hydrocarbons have been found in interstellar clouds.

There is some 02, N2, CO2. There are also a daub of Argon, hydrogen, neon, helium, and a couple of others I don't remember.\n\nAs a matter of interest, more commercial plants that product liquid nitrogen, oxygen etc, start with liquidfied air and then separate the various components.
