Isomer of C8H8O2

There should be restrictions, the molecular formula is C8H8O, and it belongs to the isomer of aromatic compounds.

That is, only those containing benzene ring structures are found).

It should be thought in the following order:

Phenols. ho-c6h4-c2h5

neighbors, between, pairs).

There are 2 -CH3 and 1 -OH on the benzene ring.

6 kinds, (you can remember this as a theorem, there are three AAB groups on the benzene ring, and there are 6 structures in total).

Aromatic alcohols: C6H5-CH2CH2-OH, C6H5-CH(OH)CH3, CH3-C6H4-CH2OH (o-, inter, pair).

Aromatic ethers. C6H5-O-C2H5, CH3-C6H4-OC3, between, pair).

If it is only a narrow isomer in the middle school range, you can find it in this way, first look at the remaining C2H3O except for phenylC6H5 as a side chain, then there are four isomerism: -CH2COOH, -CoCH2OH, -Chochoh (a ternary ring between two Cs), and -C00CH3.

2. C2H3O is split into two side chains, and each side chain can produce three isomers of the adjacent pair, which can be split into 1 methyl + 1 carboxyl group.

1. Acetaldehyde. Group + 1 hydroxy group, 1 epoxy group + 1 hydroxy group, 1 aldehyde group + 1 ethanol.

base, so that there are 3*4=12 kinds in total.

3 Split C2H3O into three side chains, 1 methyl, 1 aldehyde group, 1 hydroxyl group, such a combination can be obtained by changing the position of the three bases, so it depends on the specific requirements of the question to have the meaning of finding, otherwise the questioner is wasting the candidate's time

C7H8O contains isomers of benzene rings: CH6H5-O-CH3, C6H5-CH2-OH (hydroxyl group attached to methylene), CH3-C6H4-OH (three isomers between methyl and hydroxyl neighbors).

The molecular formula of benzene is C6H6. Although benzene should show a high degree of unsaturation in terms of hydrocarbon ratio, benzene does not possess the properties of unsaturated hydrocarbons.

In general, benzene is not easy to undergo electrophilic addition reactions such as olefins, nor is it oxidized by potassium permanganate, and is prone to substitution reactions of benzene rings, such as halogenation, nitration, sulfonation, alkylation and acylation, etc., which maintain the original structure of benzene ring.

Benzene rings are commonly drawn

A benzene ring is commonly drawn as a regular hexagon with a circle inside. The circles emphasize the delocalization of the 6 electrons and the uniform distribution of the electron cloud, which explains the homogeneity of the carbon-carbon bond length and the complete symmetry of the benzene ring.

However, this method is used to refer to other aromatic systems, such as two fused benzene rings, naphthalene, which is easily misleading.

The use of circles in benzene rings to represent delocalized double bonds was proposed by the British scientist Sir Robinson) and called them aromatic hexagons. Sir was awarded the 1947 Nobel Prize in Chemistry for his contributions to the study of natural products, and he was also the first scientist to use a curved arrow to indicate the direction of electron transfer.

Isomer Properties:

The composition and molecular weight of isomers are exactly the same, while the structure, physical properties, and chemical properties of the molecules are different.

It's also not the same, like ethanol.

and methyl ether [C2H6O].

Isomers in organic matter are divided into two categories: tectonic isomerism and stereoisomerism. Having the same molecular formula but having a different order of attachment of atoms or groups in a molecule is called tectonic isomerism. In molecules, atoms bind in the same order, while atoms or clusters of atoms.

Differing in relative positions in space is called stereoisomerism.

The isomers of C3H8O are: CH3CH2CH2OH, CH3CHHCH3, CH3-O-CH2CH3. There are 3 isomers of C3H8O, n-propanol CH3CH2CH2OH, isopropanol (CH3)2CHOH and ethylmethyl ether CH3CH2OC3.

Isopropanol, abbreviated IPA, also known as 2-propanol, is an organic compound, the chemical formula is C3H8O, is an isomer of n-propanol, is a colorless transparent liquid, has an odor similar to a mixture of ethanol and acetone, soluble in water.

C3H8 chemical nameThe chemical name of C3H8 is propane, a three-carbon alkane, the molecular formula is C3H8, and the simple formula of the structure is CH3CH2CH3. Propane is a colorless gas that can be liquefied. Propane is slightly soluble in water, soluble in ethanol and ether.

Propane is mixed with air to form a ** mixture. Present in natural gas and petroleum pyrolysis gas. Propane is chemically stable and does not easily undergo chemical reactions.

Propane is used as a refrigerant, fuel for internal combustion engines, or as a feedstock for organic synthesis.

There are 18 isomers of C8H18, as shown in the figure below

Isomers are also known as isomers. In guessing chemistry, it refers to molecules with the same molecular formula, and the chemical bonds between atoms are often the same; But the arrangement of the atoms is different. In other words, they have different "structural formulas".

Many isomers have the same or similar chemical properties, but if they are isomers of functional groups (i.e., functional groups are different), then the chemical properties are different because the chemical properties of organic matter are mainly determined by functional groups.

The isomers of C8H10 are ethylbenzene, o-xylene, m-xylene, and paraxylene. Isomers chemically refer to a compound with the same molecular formula but with a different arrangement of atoms. Compounds with the same molecular formula but different structures are isomers of each other.
