The tetrahedral intermediate reforms the ester when there are no nitro substituents on the aromatic ring because the carboxylate ion is a weaker basic (a better leaving group) than the 2,4-dinitrophenolate ion.
The anhydride is formed by the tetrahedral intermediate because the 2,4-dinitrophenolate ion, in contrast, has a weaker basic (a better leaving group) than the carboxylate ion.
Organic compounds that include one or more nitro functional group are known as nitro compounds. One of the most often used explosophores (functional groups that make a compound explosive) on a global scale is the nitro group.
One or more nitro functional groups that are physically linked to the carbon of the hydrocarbon chain or aromatic ring define the major family of organic molecules known as nitro compounds.
The great ability of the nitro group to remove electrons via resonance and inductive effect has been linked to in a number of research on its properties.
