+ H+ Electrophilic aromatic substitution is a two-step process. In the first step an electrophile, here generically shown as Y , reacts with the aromatic ring to form a resonance-stabilized carbocation intermediate. In the second step, loss of a proton from the site of attack restores aromaticity to the ring and completes the reaction. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions no XT + H H- A
