How should these chemical formulas be named, and how should this chemical formula be named?

The order in which the main functional groups are named is roughly as follows: carboxyl group, ether bond, aldehyde group, carbonyl group, hydroxyl group, double bond, triple bond, -x (x is a halogen), > nitro group.

There are both carboxyl and carbonyl groups and are named keto acids or aldehydes.

Carbonyl groups can be divided into ketone groups and aldehyde groups.

Ketoacids are compounds that contain both carboxyl and ketone groups in their molecules. According to the relative position of the carboxyl and ketone groups in the molecule, it can be divided into ketoacids, where ketoacids are intermediate products of sugar, fat, and protein metabolism in the human body. Ketoacids are a class of organic acids that play an important role in living organisms, and they play a central role in the metabolism of amino acids and the maintenance of redox states.

Aldehyde acid refers to the aldehyde group (-CHO) and carboxyl group (-COOH) in the same molecule of organic compounds, which have the properties of both acid and aldehyde.

This is called: n-butylpyridine bromide.

Cyclohexane and acetone should be solvents, and acetone may also be extractants, which is uncertain... Because I don't know if cyclohexane and acetone are miscible or not).

Acetic propionic anhydride.

The naming rule of carboxyanhydride is to call anhydride by the name of the acid that forms the anhydride, and then add the word "anhydride".

For example: CH3CO-O-Co-C2H5 - acetic acid propionic anhydride) If the two molecular acids that form the acid anhydride are the same, it is directly called "a certain acid anhydride".

Summary. What is the specific chemical formula?

What is the specific chemical formula?

Summary. One. The chemical formula and nomenclature of elemental matter.

The elemental substance that is solid at room temperature is generally represented by the element symbol, and the name of the element symbol is the name of the element, such as carbon-c, sulfur-s, phosphorus-p, sodium-na, copper-cu, magnesium-mg, iron-fe, but iodine is i2.

Noble gases use the element symbol to represent the elemental element, and the name of the element symbol is the name of the element, and the word "gas" can also be added after the name of the element, such as helium (gas)-he, neon (gas)-ne, argon (gas)-ar, etc.

The elemental substance of other gases is generally represented by the element symbol and the right subscript 2, and is named by adding the word "gas" to the name of the element symbol, such as oxygen- -02, hydrogen--h2, chlorine--c12, nitrogen--n2.

Chemical formula and nomenclature of dioxide.

In the chemical formula of oxide, the symbol of the oxygen element is written on the right, and the symbol of the other element is written on the left, that is, "the first to read and then write, and the last to read first to write" - is generally called "oxidation", such as "copper oxide", after reading "copper", then write the element symbol of copper "cu", read "oxygen" first, then write the symbol of oxygen element "0", so the chemistry of copper oxide.

Name the chemical formula.

Hello, please describe your problem specifically

One. The chemical formula and nomenclature of elemental matter that is solid at room temperature - generally use the element symbol to indicate the elemental element, and the name of the element symbol is the name of the element, such as carbon - c, sulfur - s, phosphorus-p, sodium-na, copper cu, magnesium - mg, iron - fe, but iodine is i2. Noble gases use the element symbol to represent the elemental element, and the name of the element symbol is the name of the element, and the word "gas" can also be added after the name of the element, such as helium (gas)-he, neon (gas)-ne, argon (gas)-ar, etc.

The elemental substance of other gases is generally represented by the element symbol and the right subscript 2, and is named by adding the word "gas" to the name of the element symbol, such as oxygen- -02, hydrogen--h2, chlorine--c12, nitrogen--n2. In the chemical formula of oxide and nomenclature method, the symbol of the oxygen element is written on the right, and the symbol of the other element is written on the left, that is, "the first to read and then write, and the last to read first" - is generally called "oxide", such as "copper oxide", after reading "copper", then write the element symbol of copper "cu", read "oxygen" first, then write the symbol of oxygen element "0", so the chemistry of copper oxide.

The first: 2,5-dimethyl-3-ethylheptane.

The second: 2,4-dimethyl-3-ethylhexane.

The main principles involved include: when the main chain is the same length, choose the one with more branches as the main chain;

If there are multiple branches, select the route with the lowest branch number.
