Ethane has no structural isomers and hence there is no n-ethane and iso-ethane.
The sequence goes like this:methane1, ethane2, propane3, butane4, pentane5, hexane6, heptane7, octane8, nonane9, decane10 and so on the formula for working out the hydrocarbon chain isCnH2n+2
The fourth of the methane series. Methane, ethane, propane, butane, pentane, hexane, heptane, octane, ... Fourth is butane, like in a bic lighter.
Examples: methane, ethane, propane, butane.
Butane is a gas at atmospheric pressure and room temperature. In the fuel tanks of cigarette lighters, butane welding torches, and most other butane powered heating devices, butane has been compressed to the point that it remains liquid at room temperature. When the trigger of these devices is depressed, a valve opens, allowing butane to escape from the tank, and in doing so, it's pressure drops to atmospheric pressure, and the liquid butane escaping the tank rapidly boils and becomes a gas, which is ignited by an ignition source. Strictly speaking, if the tank contained pure butane, when all the butane has evaporated, all that would be left in the tank is butane gas at atmospheric pressure. If you sprayed liquid butane on your table, and it were completely pure, the liquid would evaporate, leaving nothing behind. In reality, butane fuel is not completely pure, and may contain small amounts of all sorts of contaminants, some of which can be left behind after the butane evaporates. Some of these contaminants like methane, ethane, and propane likely would evaporate away with the butane, but other contaminants, like trace amounts of other petroleum distillates will likely remain after the butane evaporates.

The structural formula of sucrose is C12H22O11. Sucrose's common name is table sugar, and is made up of two sugar units.
Examples: methane, ethane, propane, butane.
The chemical formula of hydrogen sulphide is H2S.
A given sample of butane might contain traces of benzene, but pure butane does not.

Petroleum is a complex mixture of organic liquids called crude oil and natural gas. Crude oil and natural gas are extracted from the groundon land or under the oceans. It consists of mainly alkanes like methane , ethane, propane and butane.

The natural gas supplied by your utility company is almost pure methane. This is a chemical compound of one carbon atom and four hydrogen atoms.The stuff that comes out of a natural gas well is a mixture of hydrocarbons (mainly methane, ethane, propane, and butane) and impurities. All of the stuff besides methane is separated out (and something smelly like mercaptan added in) before the natural gas is sold to consumers.
A chemical formula that shows how atoms are arranged within a molecule or polyatomic ion and a molecular formula shows the number of the atoms that makes up the molecule.A molecular formula indicates the numbers and types of elements in one molecule of a substance. A structural formula indicates how the atoms are bonded to one another. Some examples include:water: H2O, H-O-Hcarbon dioxide: CO2, O=C=Ooxygen: O2, O=OIn a structural formula, each line represents a single covalent bond (one pair of shared electrons) between the atoms, and a double line represents a double covalent bond (two pairs of shared electrons) between the atoms.
the formula is c2h4 like a normal ethane, however it has the square brackets around it with the 'n' on the bottom right to show that it is polymer. H H l l -C- C- (with the square brackets) l l H H n
