3-Chloro-4-fluoronitrobenzene
Properties
3-chloro-4-fluoronitrobenzene, its appearance is often [specific appearance description], and it has specific physical and chemical properties. Its melting point is [melting point value], its boiling point is [boiling point value], and its density is [density value]. In terms of chemical properties, the presence of chlorine, fluorine and nitro groups in its molecular structure gives it unique reactivity. Nitro is a strong electron-absorbing group, which reduces the electron cloud density of the benzene ring and makes nucleophilic substitution reactions easy to occur; chlorine and fluorine atoms can participate in various substitution reactions under appropriate conditions, showing the characteristics of halogen atoms.
