What is the difference between propane and ethane and methophoria

All are alkanes, but contain carbon atoms ranging from 1 to 4

Methane: CH4

Ethane: C2H6

Propane: C3H8

Butane: C4H10

The chemical structure and chemical formula are different.

This is to detect a foul-smelling gas added when it leaks, so that when the liquefied gas leaks, you can find the leak and the approximate location of the leak as soon as possible. I think it should be a red flag, after all, fragrance is easily misunderstood as perfume, and the smell is easier to detect.

The chemical equation for the combustion of propane and butane in air:

c3h8+5o2=3co2+4h2o

2c4h10+13o2=8co2+10h2o

Ethane is an alkane with two carbon atoms, and propane is an alkane with three carbon atoms, so the simplest form is not the same.

The relative molecular mass of ethane, air is 29 and the relative molecular mass of ethane is 30

The data in the data are slightly different, and the measurement method of the kinetic diameter is different.

Methane molecule diameter nanometer, ethane nanometer, propane nanometer.

No melene.

Alkanes are saturated hydrocarbons, and substitution reactions are characteristic reactions;

Olefin is an unsaturated hydrocarbon, and the addition reaction is a characteristic reaction.

A, B, C refers to the number of carbon atoms, from one to ten are A, B, C, D, E, G, XING, NON, DEC and then it is represented by eleven, twelve, etc.

Therefore, A, B, and propane refer to alkanes containing one, two, and three carbons respectively (alkane refers to compounds with only carbon and hydrogen).

Their chemical formulas are CH4 respectively

C2H6 (structural formula CH3CH3).

C3H6 (structural formula CH3CH2CH3).

This is the organic matter system nomenclature.

The key is the determination of the main chain and the law of the number of carbon atoms on the main chain. These two points are different for different types of organic matter.

A, B, C refers to the number of carbon atoms in the backbone, from one to ten are A, B, C, D, E, H, G, XING, NON, and then decanter, and then it is represented by eleven, twelve, etc.

Methane, ethane, and propane are representative substances of alkanes.

It is flammable and can undergo substitution reactions.

Methane CH4 is natural gas.

I don't know anything else.

The melting point of ethane, which has a smaller molecular weight, is higher than that of propane, which is due to the fact that the intermolecular forces in a crystal depend not only on the size of the molecule, but also on the spatial arrangement of the carbon chains in the crystal. The molecular symmetry is more neatly arranged, the intermolecular attraction is larger, and the melting point is higher. Propane has poor symmetry because the carbon chain of alkanes is jagged and therefore has the lowest boiling point.

Propane, a three-carbon alkane, with the chemical formula C3H8, is usually in gaseous form, but it is generally compressed into a liquid state and then transported. ** or after natural gas treatment, propane can be obtained from refined oil. Propane is commonly used as a fuel for engines, barbecue food, and home heating systems.

In sales, propane is generally referred to as liquefied petroleum gas (LPG), which is often mixed with propylene, butane and butylene. In order to avoid accidental leaks, foul-smelling ethyl mercaptan is also commonly added to commercial LPG.

The melting point is related to molecular symmetry, and the molecular symmetry of propane is obviously not as good as that of methane and ethane.
