Yes. This one**.

You can see if you can understand it.

I'm sorry, because my negligence has a few less h's in the formula.

Is there anything you don't understand?

The loop on the far left doesn't quite understand.

Because he chose the longest chain as the main chain.

Solubility is miscible with water, miscible in ethanol, ether, etc.

Stability Stable.

Chemical properties of ethylene glycol:

Similar to ethanol, it can mainly react with inorganic or organic acids to form esters, generally only one hydroxyl group reacts first, and both hydroxyl groups can be formed into esters by increasing the temperature and increasing the amount of acid. If it reacts with nitric acid mixed with sulfuric acid, it forms nitrite. Acid chloride or anhydride tends to make two hydroxyl groups form esters.

Ethylene glycol is heated under the action of a catalyst (manganese dioxide, alumina, zinc oxide or sulfuric acid), and intramolecular or intermolecular water loss can occur.

Ethylene glycol can react with alkali metals or alkaline earth metals to form alkoxides. Usually the metal is dissolved in the diol, and only one alkoxide is obtained; If this alkyl salt (e.g. monosodium glycol) is heated to 180 200°C in a hydrogen gas stream, disodium glycol and ethylene glycol can be formed. In addition, ethylene glycol can be heated with 2 molar sodium methoxide to obtain disodium ethylene glycol.

Disodium ethylene glycol reacts with alkyl halides to form ethylene glycol monoether or diether.

Disodium ethylene glycol reacts with 1,2 dibromoethane to form dioxane. In addition, ethylene glycol is also susceptible to oxidation, and depending on the oxidant used or reaction conditions, various products can be generated, such as glycolaldehyde Hoch2cho, glyoxal OHCCHO, glycolic acid Hoch2COOH, oxalate Hoccooh, carbon dioxide and water. A glycol is different from other glycols in that carbon chain breaks can occur when oxidized by periodic acid.

Preparation method is industrially prepared by hydrolysis of ethylene oxide with dilute hydrochloric acid. It can be prepared by hydrolysis of dihaloalkanes or haloethanol in the laboratory.

The main uses of ethylene glycol: used in the manufacture of resins, plasticizers, synthetic fibers, cosmetics and explosives, and as a solvent, antifreeze in the preparation of engines.

Judging by this structure, there can only be one structure, and that is ethylene peroxide, which has a structure of CH3CH2OOH. It has only oxidizing properties and no other properties.

Ethylene glycol: Hoch2CH2OH, which has the properties of alcohol.

Monohydroxymethyl ether: CH3OCH2OH, which has the properties of alcohol and ether.

Ho-CH2CH2-OH: ethylene glycol.

It has the properties of alcohol: it reacts with Na to form sodium alk and H2, condenses it into ether, esterification reaction, polycondensation with diacid, and oxidizes it into aldehydes and acids.

CH3-O-CH2-OH: methoxymethanol.

It has the properties of alcohol and ether.

The above two are more stable, and there are two less stable substances. The two most prominent properties are the oxidizing properties of peroxides.

The structural short-form of c h is ch ch.

Acetylene is the simplest alkyne, also known as calcium carbide gas. The structural formula H-C C-H, the simple structural formula CH, the simplest formula (also known as the experimental formula) CH, the molecular formula C H, and the acetylene center C atom adopts SP hybridization. Electronic h:

c┇┇c：h。Acetylene molecular weight, gas specific gravity, flame temperature 3150, calorific value 12800 (kcal m) combustion rate in oxygen, pure acetylene burns about 2100 degrees in air, and can burn up to 3600 degrees in oxygen.

The chemical properties are very active, and can cause addition, oxidation, polymerization and metal substitution reactions.

The simple structural formula is a simple expression of the structural formula (usually only applicable to pure substances in molecular form, such as organic molecules), which should express the functional groups in the substance: as long as the carbon-hydrogen single bond is omitted, most single bonds such as carbon-carbon single bond, carbon-chlorine single bond, carbon and hydroxyl single bond can be omitted or not. (In high school chemistry, most of them follow the principle of saving if you can).

For example, the structure of propane is simply CH CH, ethylene is CH = CH, tetrachloromethane CCL, ethanol CH CH oh and so on. But carbon-carbon double bonds, triple bonds, and most rings must not be omitted. Carbon-oxygen double bonds can be omitted, such as formaldehyde HCHO.

Multiple repeating units can be combined with similar terms, such as n-butane CH (CH) CH. The branch chain can be attached to the connected carbon by another chemical bond or parentheses.

5 kinds of 6 carbons in a straight line, this is one.

5 carbons in a straight line, numbered 12345 from left to right, and the remaining one carbon is one on 2, 4, and 1 on 3, these are two.

Connect 4 carbons in a straight line, numbered 1234, and connect the remaining two carbons to No. 2, one to No. 3, or both to No. 2 (both on No. 2 and No. 3 are the same) These are two again, so there are 5 kinds in total, and if you don't understand, you can ask at any time.
