- Q: What is the derivative of benzene?
- The most important use of benzene is the preparation of ethylbenzene, followed by the preparation of cyclohexane and phenol. Benzene by substitution reaction, addition reaction, oxidation reaction generated a series of compounds can be used as the preparation of plastic, rubber, fiber, , Detergents, insecticides, etc. Approximately 10% of benzene is used as a raw material for the production of benzene-based intermediates, and benzene has good solubility as a solvent in chemical production.
- Q: Comparison of Solubilization of Benzene and Its Derivatives
- The chemical properties of benzene are: under certain conditions, benzene can be with hydrogen, bromine, concentrated nitric acid, concentrated sulfuric acid and other substances chemical reaction, benzene can also be generated in the air combustion of carbon dioxide and water. I hope my answer can be helpful for your study!
- Q: Benzene derivatives are named from small groups to large groups or from large to small. The following three examples contradict each other ah!
- The first should be called p-ethyl toluene, 2,3 pairs, should start from small groups.
