Organic Chemistry

Organic chemistry is the chemistry of carbon. The classification of organic chemical substances is mainly based on their decisive role, which can represent the different groups of chemical substances. Can be divided into: alkanes, alkenes, alkynes, aromatic hydrocarbons (above hydrocarbons); halogenated hydrocarbons, alcohols, phenols, ethers, aldehydes, ketones, carboxylic acids, carboxylic acid derivatives, amines, nitro compounds, nitrile Class, sulfur-containing organic compounds (such as mercaptans, thioethers, thiophenols, sulfonic acids, sulfones, and sulfoxides), phosphorus-containing organic compounds and other elemental organic compounds, heterocyclic compounds, etc. (the above are hydrocarbon derivatives)

Hydrocarbons and Derivatives

Hydrocarbons generally refer to hydrocarbons and are a type of organic compound. This compound consists of only two elements, carbon and hydrogen, including alkanes, alkenes, alkynes, cyclic hydrocarbons, and aromatic hydrocarbons, and is the matrix of many other organic compounds. There are many types of hydrocarbons, which can be divided into: open-chain hydrocarbons, alicyclic hydrocarbons, aromatic hydrocarbons. Hydrocarbon derivatives are compound compounds that continue to combine with other elemental substances or other compounds. Derivatives of hydrocarbons are more colorful and diverse. It mainly combines with oxygen, chlorine, bromine and their hydrides to form a huge derivative community.

Carboxylic Acids and Derivatives

Carboxylic acid is the most important type of organic acid. A class of compounds with the general formula RCOOH or R (COOH) n, functional group: -COOH. In organic chemistry, compounds in which the hydroxyl group in the carboxylic acid molecule is replaced with other atoms or atomic groups such as halogen and amino groups are called carboxylic acid derivatives, including acid halides, acid anhydrides, esters, and amides.


Compounds containing amide bonds are called amides. Amides can be regarded as nitrogen-containing derivatives of carboxylic acids, as well as derivatives of ammonia or amines. Amides can be divided into amides, imides, lactams and N-substituted amides according to their structure. It is mainly used as an industrial solvent, used in the production of vitamins and hormones in the pharmaceutical industry, and also used in the manufacture of insecticidal amidine. In organic reactions, dimethylformamide is not only widely used as a solvent for the reaction, but also an important intermediate in organic synthesis.
