EAS Series: Video 3
This video will start by showing you a quick comparison of alkene halogenation versus aromatic halogenation: bromination and chlorination. This video will show you the aromatic halogenation mechanism from the role of the Lewis Acid catalyst and formation of the super-electrophile, through the entire mechanism of adding halogen to benzene. Also shown is a break down of the reaction mechanism for aromatic halogenation using Cl2 with the Lewis acid catalyst AlCl3.

Alkene Reactions Series: Video 3
Halogenation of alkenes is the reaction in which a double bond is broken and replaced by a vicinal dihalide – 2 halogen atoms added to neighboring carbons. This reaction follows a pattern of anti addition.

The goal of this video is to help you understand rather than memorize concepts related to the halogenation mechanism. This video addresses dihalide polarization, bromonium/chloronium bridge formation, addition to cyclic and asymmetrical starting alkenes.
