Practice Problem: Electrophilic Aromatic Substitution Rates

The video tutorial explains the bromination of aromatic compounds with different functional groups, focusing on drawing the resulting products and ranking the reactions by speed. It covers the directing capabilities of functional groups, such as halogens and hydroxyl groups, and their effects on regioselectivity and reaction kinetics. The tutorial also discusses the role of electron withdrawing and donating groups in stabilizing or destabilizing the arenium ion intermediate, affecting the reaction speed.

Discuss the role of electron donating groups in the speed of electrophilic aromatic substitution reactions.

What is the order of reactivity for the different substituents in electrophilic aromatic substitution, and why?
