WebbStep 1: Nitric acid (HNO 3) is protonated by sulfuric acid which causes the loss of a water molecule and formation of a nitronium ion, a strong electrophile. Steps 2 and 3: … Webb9 nov. 2024 · Electrophilic aromatic substitution (EAS) reactions proceed through a two-step mechanism. In the first step, the aromatic ring, acting as a nucleophile, attacks an electrophile (E+). This is the slow (rate-determining) step since it disrupts aromaticity and results in a carbocation intermediate. chaotic how to play
