Br-Br FeBr3 Br+-FeBr4 1Slow An electron pair from the benzene ring attacks the positively polarized bromine,forming a new C-Br bond and leaving a nonaromatic carbocation intermediate. A base removes H+from the carbocation intermediate, and the neutral substitution product forms as two electrons from the C-H bond move to re-form the aromatic ring. 2Fast +HBr FeBr3
