Skeletal diagram Reactions[ edit ] Spectrum of the blue flame from a butane torch showing CH molecular radical band emission and C2 Swan bands When oxygen is plentiful, butane burns to form carbon dioxide and water vapor; when oxygen is limited, carbon soot or carbon monoxide may also be formed. When there is sufficient oxygen:
It is a colorless gas at room temperature and pressure. The molar mass of this compound is about It has a gasoline like odor.
It belongs to the group alkanes since it has no double bonds in its structure. Butane is a nonpolar compound. Therefore, it is not dissolved in polar solvents or water. Butane molecules may exist in two different structural isomers.
They are n-butane and isobutane. Structural Isomers of Butane Butane is highly flammable. It is easily liquefied. Since the boiling point of butane is about 1oC or less this butane liquid is quickly vaporized at room temperature.
When there is enough oxygen present in the surrounding, butane can undergo complete combustion, forming carbon dioxide and water vapor along with heat energy. But if the oxygen is not enough, then butane will undergo incomplete combustion, producing carbon monoxide and carbon dust. Butane can be added to gasoline in order to fasten the vaporization of gasoline.
This is one of the major uses of butane. It can also be used as a solvent for extractions since butane is highly nonpolar and less reactive. In addition, butane is used as a fuel in small scale applications. What is Butene Butene is a hydrocarbon that has the chemical formula C4H8.
It has a slightly aromatic odor. Butene is an alkene. The major source of butene is crude oil. Butene is present in crude oil as a minor constituent. Butene can be found in several isomers.
However, butene has one double bond between two of the carbon atoms. The molar mass of butene is about Cis-trans Isomerism of Butene The isomerism of butene occurs either as structural isomerism or stereoisomerism.
The position of the double bond decides the structural isomerism. Moreover, the branched structure isobutylene is another structural isomer of the linear butene molecule. Stereoisomerism occurs according to the differences in the position of alkyl groups at allylic carbon atoms.
This is called geometrical isomerism. Butene is produced in petroleum refining. The production of butene is done through cracking reaction.
This is the breakdown of long chain hydrocarbons into small hydrocarbon molecules. Butene is a flammable gas and can be used as a fuel. Butene is an important monomer in the production of polymers. The double bond present in butene allows it to undergo polymerization which will eventually produce a polymer molecule.
Similarities Between Butane and Butene Butane and butene are hydrocarbons. These are gases at room temperature and pressure. Both are colorless gases. Butane and butene can be obtained from petroleum refining processes.
Both are highly flammable. Butane is a hydrocarbon that has the chemical formula C4H Butene is a hydrocarbon that has the chemical formula C4H8.Butane (/ ˈ b juː t eɪ n /) is an organic compound with the formula C 4 H 10 that is an alkane with four carbon atoms.
Butane is a gas at room temperature and atmospheric pressure. The term may refer to either of two structural isomers, n-butane or isobutane (also called "methylpropane"), or to a mixture of these isomers.

Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.
The molar mass of the butane gas was calculated by dividing the mass of butane gas in grams(g) by the moles of butane gas( moles). g/moles= g/mole= molar mass of butane gas. The molar mass of butane gas was calculated to be g/mole.
Gas Laws and the Molar Mass of Butane CHEM 30A The Erlenmeyer flask is initially full of water. The butane gas bubbles released from the butane cylinder displace the water in the flask, lowering the water level inside the flask (and raising the water level in the beaker).
May 11, · Best Answer: All you do is add up the molar masses of the carbons and hydrogens in the formula. Most peiordic tables show the molar masses of elements (also called their molecular weights) underneath their chemical symbols.
4(molar mass of carbon) + 10(molar mass of hydrogen) = 4( g/mol) + 10( Status: Resolved.
