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. WebDefinition 1 / 54 *The reaction intermediate is a resonance-stabilized carbocation. *The First step involves addition of an electrophile to the benzene ring. *The aromatic ring acts as a nucleophile in the first step. -Also note: It is the first step of the reaction that is slow and rate-determining.

WebDec 29, 2014 · EAS reactions are classified as activating when describing the effect on the EAS reaction of occurring multiple times on the same ring. For deactivating effects, the R group inhibits the possibility of further … WebThe high reactivity of anisole, for example, requires that the first two reactions be conducted under very mild conditions (low temperature and little or no catalyst). The nitrobenzene reactant in the third example is very unreactive, so rather harsh reaction conditions must be used to accomplish that reaction.
