Eas reactivity
WebMay 3, 2024 · Which EAS (electrophilic aromatic substitution) reactions does nitrobenzene show? We know that nitrobenzene is particularly deactivated towards most such reactions, as the nitro group is strongly electron withdrawing via resonance and inductive effects. WebNov 20, 2024 · To build on Tyberius' point: reactivity (reaction rate, determined by activation energy) is determined not only by the energy of the starting material, but also the energy of the transition state (or intermediate, by the Hammond postulate). Obviously, this depends on the exact reaction pathway under consideration.
