What is the molecular formula and structure of isobutane?

The molecular formula of isobutane: C H, the structure is simplified: ch ch(ch )ch.

It is a colorless flammable gas at room temperature and pressure. Melting point. Boiling point. Slightly soluble in water, soluble in ethanol, ether, etc. with air to form a sexual mixture, the limit is volume).

It mainly exists in natural gas, refinery gas and cracking gas, which is obtained by physical separation, and can also be prepared by isomerization of n-butane. It is mainly used to hydrocarbonize with isobutylene to produce isooctane, as an improver for gasoline octane number. It can also be used as a refrigerant.

Physical properties of isobutane: appearance and properties: colorless, slightly odorous gas. Melting point ( ) relative density (water = 1): ; Boiling point ( ) relative vapor density (air = 1): .

Chemical properties of isobutane: flammable gas. Mixed with air can form a first-class mixture, and there is a danger of burning when exposed to heat sources and open flames.

It reacts violently in contact with oxidants. Its vapor is heavier than air, can spread to a considerable distance at a low place, and will catch fire and ignite when exposed to an ignition source.

Isobutane and n-butane are isomers of each other, so its molecular formula is the same as n-butane, which is: C4H10

The structure of isobutane is as follows:

ch3-ch-ch3

.ch3

The simple formula of isobutane structure is CH3-CH-CH3. Isobutane and n-butane are isomers of each other, so its molecular formula is the same as n-butane, which is: C4H10

Isobutane is a colorless flammable gas, slightly soluble in water, and stable in nature. Present in oil and gas. Industrially, it is produced by petroleum cracking, and n-butane can also be obtained by isomerization.

Isobutane is mainly used in the preparation of isooctane as an improver of gasoline octane number; It is also used as a refrigerant.

Isobutane narrativeIt is an industrial isobutane developed with high-quality natural gas as raw material, and can be arbitrarily blended to meet different uses of propellants according to needs. Isobutane for industrial use, developed with high-quality natural gas as raw material, can be arbitrarily blended to meet different uses of propellants according to needs, which can be used to replace Freon CFC, and its ODP value and GWP value are zero, which is an ideal environmentally friendly product.

The simple formula of ethane structure is CH3CH3. The second member of ethane alkane in the same series is the simplest hydrocarbon containing carbon-carbon single bond, the structural formula is CH3CH3, the difference is that the structural formula of ethane embodies 6 CH single bonds and a CC single bond, while its structural formula is only written as CH CH, which cannot directly obtain the bonding in its molecule, but it can still be indirectly deduced.

Characteristics of ethane structureThe cc single bond of ethane can rotate freely, if one c atom in ethane does not move and the other rotates freely around the cc single bond, then the 3 Hs on one C atom can have an infinite number of spatial arrangements relative to the 3 Hs on the other C atom, ethane is present in some natural gas at 5 to 10 percent and is second only to methane and is present in oil in a dissolved state.

The different arrangement forms of the atoms or groups in the molecule in space due to the rotation of the single bond are called conformation, and each conformation is called a conformational isomer, because the cc single bond rotates freely, ethane can have countless conformations, and the dominant conformation of ethane is cross, at this time, the h distance on the two c atoms is the farthest and the repulsion between each other is the smallest.

The structure of isopentane is as follows: CH3CH2CH(CH3)2.

Isopentane (isopentane, 2-methylbutane), also known as 2-methylbutane, chemical formula C5H12, colorless and transparent volatile liquid, with a pleasant aromatic odor. It is mainly used in organic synthesis and is also used as a solvent.

Product Use: It can be used as a solvent for catalysts in polyethylene production, a blowing agent for expandable polystyrene, and a polyurethane foam.

The blowing agent of the system is excitation and deasphalting solvent.

When used as a solvent, it is used with pentane, hexane and heptane.

etc., the solubility is slightly worse than pentane. The octane number of the product.

High, vertical bends can be used as car and jet fuel.

IsopentaneThe structure is simplifiedYes: CH3CH2CH(CH3)2.

Product Use: It can be used as a solvent for catalysts in polyethylene production, a blowing agent for expandable polystyrene, and polyparasakura urethane foam.

Foaming agent, deasphalting solvent, etc.

When used as a solvent, it is used with pentane, hexane and heptane.

The solubility is slightly worse than that of pentane. The product octane or Qiyuan alkane number.

High, can be used as automobile, aircraft fuel.

The butane structure formula is shown in the figure below:

Butane, also known as n-butane, a straight-chain alkane with 4 carbons in the molecule, is a general term for two alkane hydrocarbons with the same molecular formula (C4H10), butane is a flammable, colorless, easily liquefied gas at room temperature and pressure, forming a ** mixture with air. Butane includes n-butane and isobutane (2-methylpropane).

Nature

Butane can be made into maleic anhydride, acetic acid, acetaldehyde, etc. by catalytic oxidation; Halobutane can be produced by halogenation; Nitrobutane can be obtained by nitrification; Carbon disulfide can be produced by catalysis at high temperatures; Hydrogen can be produced by water vapor conversion. In addition, butane can also be used as a motor fuel admixture to control volatile components; It can also be used as a heavy oil refined deasphaltant; wax precipitants in oil wells; It is used as a spilling agent for secondary petroleum**, a resin foaming agent, a refrigerant for converting seawater into fresh water, and an olefin agent for Geler polymerization solvents.

Isobutane is an organic compound with the chemical formula C4H10, and its molecular structure consists of four carbon atoms and ten hydrogen atoms. Specifically, the molecular structure of isobutane can be expressed by the following abbreviated formula:

ch3-ch(ch3)-ch2-ch3

Among them, CH3 represents a methyl group, that is, a unit composed of one carbon atom and three hydrogen atoms; CH stands for an ethyl group, which is a unit made up of two carbon atoms and five hydrogen atoms. Therefore, the structure of isobutane can be described as a methyl group and an ethyl group attached to the same carbon atom, and the relative vacancies of these two groups make isobutane asymmetrical, which is also its special manifestation in chemical reactions. At room temperature, isobutane is a colorless and transparent liquid with strong volatility and flammability, and is widely used in industrial production and scientific research.

<> methane has the chemical formula ch where the outermost shell of the carbon atom has 4 electrons, the outermost shell of the hydrogen atom has 1 electron, a carbon atom forms 4 pairs of shared electron pairs, and a hydrogen atom forms a pair of shared electron pairs.

The central atom of methane is a carbon atom, and the valence electrons on the carbon atom all form a covalent bond, which belongs to the structure of the ABN type, and when n=4, the molecule is a tetrahedral structure, so methane is a tetrahedral configuration.
