Methanol: Because it was first discovered in distilled wood, it is commonly known as "wood alcohol" or "wood essence", also known as hydroxymethane.

There are many types of organic compounds, which can be divided into two categories: hydrocarbons and derivatives of hydrocarbons. According to the carbon framework structure of organic molecules, they can also be divided into three categories: open chain

There are very few elements that make up organic compounds, besides carbon, there are also a few elements such as hydrogen, oxygen, sulfur, nitrogen, phosphorus, and halogens. But the number of organic compounds is extremely large, with over 10 million sp

There are two main reasons for the large number of organic compounds: (1) carbon atoms can combine with each other in various ways to form stable, linear, branched, or cyclic compounds of different lengths

For the chemical discipline mainly engaged in the study of compound molecules, in addition to general chemical terminology, it is also necessary to give each compound molecule its own name, which has exceeded tens of millions and is still increasing day b
