What is the difference between carbonyl and ether bonds, and what is the difference and connection b

1. The composition is different.

The carbonyl group is an organic functional group formed by two atoms, carbon and oxygen, linked by double bonds.

A carbonyl group is an organic compound that is made up of two hydrocarbon groups linked by one oxygen atom.

2. The general style is different.

Carbonyl: c=o

Ether bonds: r—o—r

When r and r are the same, it is called a simple ether; When R is different from R, it is called mixed ether. If R and R are aliphatic hydrocarbons, they are aliphatic ethers; R or R is an aromatic hydrocarbon, and it is an aromatic ether.

Carbonyl group (tāng jī) (carbonyl group) is an organic functional group (c=o) formed by the double bond of two atoms, carbon and oxygen. It is a component of functional groups such as aldehydes, ketones, carboxylic acids, carboxylic acid derivatives, etc.

Physical properties: strong infrared absorption.

Chemical properties: Due to the strong electron-absorbing properties of oxygen, nucleophilic addition reactions are prone to occur on carbon atoms. Other common chemical reactions include: nucleophilic reduction, aldol condensation.

Structure and properties of metal carbonyl complexes.

Most metal carbonyl complexes are insoluble in water. For example, nickel tetracarbonyl has a solubility of only g 100 ml (at 10°C), but it is soluble in most organic solvents, as well as aqua regia and nitric acid.

The bond between the carbonyl group and the metal is a synergistic bond of the feedback bond and the bond. The unbonded electron pairs of the carbon atom form a bond with the mixed orbital domain of the metal spd, while the metal-filled d d orbital domain and the * antibonding molecular orbital domain in the CO ligand form two bonds. However, the bond formation condition is that the metal atom must have d orbital electrons, and the metal needs to have a lower oxidation state (<+2).

The bond between the metal and the CO weakens the bond between carbon and oxygen, making it weaker than the bond between carbon and oxygen in carbon monoxide.

In carbonyl** complexes, the distance between the metal and the carbon atom is shorter, generally less than , and less than the distance between the metal and the alkyl carbon in general

Ether bonds. An organic compound consisting of an oxygen atom linking two hydrocarbon groups. The general formula is r—o—r.

When r and r are the same, it is called a simple ether; When R is different from R, it is called mixed ether. If R and R are aliphatic hydrocarbons, they are aliphatic ethers; R or R is an aromatic hydrocarbon, and it is an aromatic ether.

Due to the existence of ether bonds, ethers can also undergo some special reactions under certain conditions.

Ethers can form salts with strong acids and complexes with electron-deficient compounds

1. At higher temperatures, strong acids can break ether bonds (generally break the bonds between oxygen and smaller hydrocarbon groups, and the most effective reagent is concentrated hydroiodic acid or hydrobromic acid).

2. Alcohol can be dehydrated between molecules to form ether under the catalytic action of concentrated sulfuric acid.

The nature of the carbonyl group is relatively reactive and can undergo many reactions. Functional group for.

r-c=or

The ether bond is not active enough. The functional group is r-o-r.

A bond is formed between two atoms, and a group generally refers to a group that has characteristics in the spatial structure and has its own special role. An ether bond is just a connection between two atoms, not only without an ether group, but also without an alkyne group or an alkene group. Reputation

Ether is a hydrocarbon group in the hydroxyl group of alcohol or phenol.

The product of substitution, the general formula is r-o-r', r and r' can be the same or different. The same one is called simple ether or symmetrical ether; The different ones are called mixed ethers.

Classification of ethers. Two ethers with the same hydrocarbon group are called symmetrical ethers, also called simple ethers. Two ethers with different hydrocarbon groups are called asymmetric ethers, and wheel chains are also called mixed ethers.

Depending on the category of the two hydrocarbon groups, ethers can also be divided into aliphatic ethers and aromatic ethers.

In aliphatic ethers, the molecule is not made up of oxygen atoms.

The ether that combines with carbon atoms to form a cyclic ether structure is called an acyclic ether, and can also be subdivided into saturated ether and unsaturated ether. The ether in which the oxygen atoms and carbon atoms are combined to form a cyclic ether structure is called a cyclic ether. The oxygenated ether on the ring is called an inner ether or epoxy compound.

A large cyclic ether containing multiple oxygen is called a crown ether because it resembles a crown.

Structural formula of ester bond and ether bond: 3'—oh， 5′—oh。

Press C to connect 4 covalent keys.

o=c=0 is the ether bond, -ch=o is the aldehyde group, and -ch2-oh is the carbonyl group.

O=Cr-OH is the carboxyl group.

R-CH2-O-Cr=O is an ester group. The representative phosphodiester bond is the nucleotide.

Bonds between nucleotides. It is important to note that phosphodiester bonds are chemical groups, not covalent or ionic bonds in the chemical sense.

Physical. Esters are insoluble in water and soluble in ethanol.

and organic solvents such as ether, which are generally less dense than water. Lower esters are liquids with an aromatic odor.

Low molecular weight esters are colorless and volatile aromatic liquids, higher saturated fatty acid monoesters are often colorless and odorless solids, and esters formed by higher fatty acids and higher fatty alcohols are waxy solids. The melting and boiling points of esters are lower than those of the corresponding carboxylic acids. Esters are generally not soluble in water, but soluble in various organic solvents.

Low molecular weight esters can be used as solvents for many organic compounds and can also be used as solvents for varnishes.

Hydroxyl and ether bonds have electron-withdrawing induction effect and electron-donor conjugation effect, in which the electron-donating ability of the conjugation effect is stronger than that of the induction effect.

Hydroxyl is a common polar group with the chemical formula -OH. The hydroxyl group has some similar properties to water, the hydroxyl group is a typical polar group that can form hydrogen bonds with water, and exists in the form of negatively charged ions (oh-) in the aqueous solution of inorganic compounds, called hydroxides. Hydroxyl groups are mainly divided into alcohol hydroxyl groups, phenolic hydroxyl groups, etc.

The alcohol hydroxyl group is connected with the Bo, Yuranzhong or tertiary carbon atom as Bozhen modified alcohol, secondary alcohol or tertiary alcohol, which can be divided into a hydroxyl alcohol (monool) and polyhydroxyl alcohol (polyol) according to the number of hydroxyl groups contained in the alcohol molecule.

The acidity of the alcohol hydroxyl group is weakened in the order of primary, secondary and tertiary alcohols, therefore, in the reaction of -OH bond breakage, its reaction speed decreases sequentially, in the R-OH bond cleavage reaction, the reaction speed of tertiary alcohols is faster than that of primary and secondary alcohols, and under control, primary alcohols are oxidized to aldehydes (but the generated aldehydes will be converted into carboxylic acids with a stronger oxidant); secondary alcohols oxidize to ketones (usually stable and not further oxidized); In general, tertiary alcohols are not easily oxidized.

Ether bond structure: c o c.

Ether (mí, English: ether) is a class of organic compounds with ether bonds. Ether bonds are made up of an oxygen atom that joins two alkyl or aryl groups and can be seen as the replacement of hydrogen on an alcohol or phenolic hydroxyl group by a hydrocarbon group. The general formula of ether is: r o r'。

Ether envy compounds have a wide range of applications in organic chemistry and biochemistry, and they can also be used as linking fragments of sugars and lignin. Among them, the most widely used compound is diethyl ether, which is mostly used in organic solvents and medical anesthetics. Because of its versatility, we often refer to diethyl ether as "ether" for short.

Ether is the product of the substitution of hydrogen in the hydroxyl group of alcohol or phenol by a hydrocarbon group, and the general formula is r-o-r', r and r' can be the same or different. The ether that is the same as the two is called symmetrical ether, also called simple ether or single ether; Ethers that are not the same between the two are called asymmetric ethers, also called mixed ethers or mixed ethers. If r, r'The carbon and grandchild atoms at both ends of an organic group are called ring ethers, such as ethylene oxide.

Most ethers are colorless liquids at room temperature, with fragrance, low boiling point, lighter than water, and stable in nature. Ethers generally have anesthetic effects, such as ether is a commonly used inhalation anesthetic in clinical practice.
