What is the reason for chemical stupidity?

The first thing to correct is that organic chemistry, including chemistry, is not stupid, only benzene. First of all, what are organic compounds? We turn most compounds containing only carbon, hydrogen and other elements into organic compounds, except for a few inorganic compounds such as carbonate. Benzene is one of organic compounds. Benzene is a special organic compound, belonging to aromatic hydrocarbons (unlike aliphatic organic compounds, aliphatic compounds are chain-like and aromatic hydrocarbons are cyclic). It is a ring composed of six carbon atoms, each of which is connected to a hydrogen atom. According to the universality of organic compounds, carbon atoms must be connected by four bonds, so the bonds between carbon atoms are not simple carbon-carbon single bonds or carbon-carbon double bonds, but special bonds between single bonds and double bonds, so there is no difference between each carbon-carbon bond in benzene. From the atomic point of view, this is benzene.

Physically, benzene is a colorless and transparent liquid at room temperature. At room temperature, the density is generally 0.885g/cm3, the boiling point is 80. 10℃, and the melting point is 5.53℃. It is volatile, so we call it aromatic hydrocarbon, because benzene ring has a strong fragrance. Toxic. Insoluble in water, soluble in organic solvents such as ethanol and ether.

Chemically speaking, the hydrogen atom on benzene is easy to be substituted, so substitution reaction is easy to occur. Under more severe conditions, benzene can also undergo the same addition reaction with olefins to form cycloalkanes. Similarly, almost all organic compounds are flammable, and benzene is easily oxidized.

Of course, the most important thing is that his chemical formula C6H6 is cyclic, as I said above. You can ask me about the details and I will send it to you. It's not easy to send it.

You can ask questions and hope to adopt them.
