WebExpert Answer. 1. Explain, using structures, why aniline is considered a strong activator towards EAS (electrophilic aromatic substitution) reactions and nitrobenzene is considered a strong deactivator. NH2 Aniline Nitrobenzene 2. Draw the reaction and mechanism of the sulfonation of benzene using concentrated fuming sulfuric acid. WebSubstituents and their Directing Effects in EAS Reactions. Electron donating groups (D) direct the reaction to the ortho- or para-position, which means the electrophile substitutes for the hydrogen on carbon 2 or carbon 4 relative to the donating group. The withdrawing …
