As for the chemical properties, its activity can be explored. Amino group (-NH2O) coexists with nitro group (-NO2O) and trifluoromethyl group (-CF
Due to the presence of amino groups, the nitrogen atom of the amino group attacks the carbon atom of the halogenated hydrocarbon with lone pairs of electrons, and the halogenated atom leaves to form a new carbon-nitrogen bond. This is a common example of nucleophilic substitution. The strong electron absorption of the
nitro group decreases the electron cloud density of the benzene ring and changes the activity of the electrophilic substitution reaction of the benzene ring. Although the benzene ring has a conjugated system, the check point of the electrophilic attack is very different from that without the nitro group under the influence of the nitro group.
