When speaking of compounds, the allusion is generally made to chemical compounds, that is, to substances that are made up of two or more chemical elements that combine in a certain way and proportion.
There are thousands of examples of chemical compounds around us, natural and synthetic, each with its own characteristics. From the table salt or sugar with which we season what we eat daily, to the soap and bleach that we use to clean, to the medicines we take to ease our pain or cure infections, they are made up of different chemical compounds.
Since there are so many chemical compounds, it is common to try to sort them in some way. In general, they are divided into two large groups: organic compounds and inorganic compounds :
- Organic: They contain at least carbon and hydrogen in their molecule, they are among the important substances such as hydrocarbons, classic fuels; proteins, or fats.
- Inorganic: They do not contain carbon as a central element, but combine other elements (such as nitrogen, sulfur, iron, oxygen or potassium), to form salts, oxides, hydroxides, and acids. Anyway cable clarifies that there are also organic acids and salts.
Depending on the type of bond that occurs between the elements, you can have ionic or covalent compounds:
- Ionic compounds: They are held together with the cation and the anion by the attraction caused by the charge difference.
- Covalent compounds: Their electrons are shared.
The chemical compounds usually represented by the structural formula or semi-developed . Three-dimensional models are also very useful for understanding how chemical compounds are formed, especially if they are very complex molecules with specific folding, such as proteins.
