Can carboxylic acids react with sodium? Carboxyl and sodium reactions

Yes, because carboxylic acids contain carboxyl groups, which are more acidic. The equation is: 2R-CoOh + 2Na = 2R-Coona + H2 An organic compound composed of a hydrocarbon group and a carboxyl group is called a carboxylic acid.

The boiling point of saturated monocarboxylic acids is even higher than that of alcohols with similar relative molecular mass. It is acidic and reacts with alkali to form salts. It is generally reacted with phosphorus trichloride to form acid chloride; dehydration with phosphorus pentoxide to produce anhydride; reacts with alcohol under acid catalysis to form esters; reacts with ammonia to form amides; Alcohol is generated by reduction with lithium aluminum tetrahydride (LiALH4).

It can be prepared by oxidation of side chains of alcohols, aldehydes, unsaturated hydrocarbons, aromatic hydrocarbons, etc., or by nitrile hydrolysis, or reaction of Griard reagent with dry ice. Application: Low fatty acids are important chemical raw materials, which are produced on a large scale in industry.

Pure acetic acid can be used to make man-made fibers, plastics, flavors, medicines, etc. Higher fatty acids are the basis of the oil industry. Dicarboxylic acids are widely used in the fiber and plastics industries.

Certain aromatic acids, such as benzoic acid and salicylic acid, have a variety of important industrial uses.

Yes, for example, isn't acetic acid a carboxyl group in acetic acid? Sodium acetate can be generated, which is a reaction between carboxyl groups and sodium.

Of course I can, carboxylic acid has the general characteristics of acid.

Carboxyl and sodium do not react, carboxyl is the basic chemical group in organic chemistry, all organic acids containing carboxyl groups can be called carboxylic acids, composed of one carbon atom, two oxygen atoms and one hydrogen atom, the chemical formula -COOH. For example, acetic acid (CH3-COOH) and amino acids contain carboxyl groups, and these carboxyl groups are directly linked to the hydrocarbon groups, which are called carboxylic acids.

Sodium is a metal element, located in the 3rd period, group a in the periodic table, is a representative of alkali metal elements, soft texture, can react with water to form sodium hydroxide, release hydrogen, chemical properties are more active. Sodium is widely distributed in the form of salt on land and in the sea, and sodium is also one of the important components in human muscle tissue and nerve tissue.

Reaction, -OH in the carboxyl group is combined with Na to form hydrogen.

As follows:

1. Reaction between sodium and dilute hydrochloric acid: sodium rotates sharply, and a large number of bubbles emerge from the solution. Chemical reaction.

The equation is 2Na+2HCl=2NaCl+H2.

2. The reaction equivalent to sodium and hydrogen ions, the phenomenon is more violent than the reaction with water, and the phenomenon can be summarized by floating melting: floating on the liquid surface, swimming around, making a sound, and melting into a small ball.

3. Ionic reaction.

The equation is: 2Na+2(H+)=2(Na+)+H2. Sodium into solution with NaOH:

Sodium rotates in the solution, a large number of bubbles emerge from the solution, and the chemical reaction equation is: 2Na+2H2O=2NaOH+H2; The ionic reaction equation is: 2Na+2(H+)=2(Na+)+H2.

Sodium metal. Reacting with hydrochloric acid, does sodium react with acid or water first?

Sodium first reacts with hydrogen ions in hydrochloric acid; HCl is a strong acid with 100% ionization of hydrogen ions. Water is a weak electrolyte.

Hydrogen ions are also ionized. The reaction between sodium and hydrochloric acid is essentially a reaction with hydrogen ions to produce hydrogen and sodium salts.

Chemical properties of sodium.

It is very lively, and when it is heated at room temperature and heated, it is combined with oxygen, and reacts violently with water, and occurs when the amount is large**. Sodium can also be found in carbon dioxide.

It reacts with low-level alcohols to produce hydrogen, and liquid ammonia, which has a weak ionization ability.

1. Sodium: a compound with functional groups hydroxyl and carboxyl groups.

2. Sodium hydroxide: compounds with functional groups hydroxyl, carboxyl, ester and halogenated groups.

3. Sodium carbonate: carboxylic acids and phenols.

4. Sodium bicarbonate: a compound with a functional group carboxyl group.

The properties of the carboxyl group are not a simple addition of the carbonyl and hydroxyl groups. For example, the carbonyl group in the carboxyl group becomes very inactive under the influence of the hydroxyl group, and does not undergo addition reaction with nucleophiles such as HCN and NaHSO3, while its hydroxyl hydrogen is easier to dissociate than the alcohol hydroxyl hydrogen, showing weak acidity.

Reduction reaction of carbonyl group:

Aldehydes or ketones are reduced to the corresponding alcohols under enzyme catalysis, and the alcohols can be further combined with glucuronic acid to form glycosides, or sulfate esters to form water-soluble molecules, which are easy to excrete.

For example, chloral hydrate is reduced and metabolized into the active product trichloroethanol, which is excreted by binding with glucuronic acid. Ketone carbonyl is a common group in the structure of drugs, ketones are difficult to be oxidized in the body, and are usually produced in the body by the action of ketone reductase to produce secondary alcohols.

Since aldehydes are susceptible to oxidation, aldehydes are rarely reduced to primary alcohols. The aliphatic and aromatic asymmetric ketone carbonyl groups are catalyzed by enzymes and are reduced to a chiral hydroxyl group in a three-dimensional specificity.

Acids are a general term for a class of chemical compounds.

The narrow definition of acid in chemistry is: the cations ionized in the solution of the sparrow are all hydrogen ion compounds. Proposed by Arrhenius, this theory is known as Arrhenius' acid-base theory.

Broadly defined: a substance capable of accepting electron pairs.

Most of these substances are soluble in water, and a small part, such as silicic acid, is insoluble in water. An aqueous solution of an acid generally conducts electricity, and its conductive properties are related to its degree of ionization in water.

Some acids exist in the form of molecules in water and do not conduct electricity; Some acids dissociate into positive and negative ions in water, which can conduct electricity.

Acid-base proton theory: a broader definition that can provide protons in the reaction is an acid, and vice versa is a base, this definition is called Bronster (J.). m.

Bronsted) - Laurie (T.). m.Lowry) acid.

This theory is called the acid-base proton theory.

Bronsted acidity is a concept in acid-base proton theory that represents the ability of a substance to release protons (H+). Specifically, if a substance Ha becomes A- after emitting H+, its bronsted acidity is the equilibrium constant of the reaction Ha = H+ +A-. The larger the equilibrium constant, the easier it is for HA to release protons, and the more bronsted it is to be bronsted.

Lewis's acid-base theory: by the American Lewis (G. Louis). n.

Lewis). This theory defines an acid as a recipient of electron pairs, known as Lewis acid, and has a broader range. The acid-base reaction is a reaction in which a coordination covalent bond is formed between the electron-pair acceptor and the electron-pair donor.

Soft and hard acid-base theory: The soft and hard acid-base theory is an extension of Lewis's acid-base theory. In the theory of soft and hard acids and bases, acids and alkalis are classified as "hard" and "soft" respectively.
