Practice-Problem: Three-Reaction Pathway

The video tutorial covers a sequence of three chemical reactions applied to a starting material. It begins with radical bromination, highlighting the regioselectivity of bromine in targeting the most substituted carbon. The second reaction involves E2 elimination using methoxide, emphasizing the formation of the most thermodynamically stable alkene. The final reaction is dihalogenation, where the addition of bromine across a double bond is discussed, including the stereochemical outcomes. The tutorial provides a step-by-step analysis of each reaction, focusing on the mechanisms and expected products.
