Markovnikov vs Anti-Markovnikov in Alkene Addition Reactions

Markovnikov vs Anti-Markovnikov in Alkene Addition Reactions Tutorial by Leah4Sci for Organic Chemistry studentsv

Markovnikov’s Rule is a very important pattern to both understand and recognize when studying alkene addition reactions. What is Markovnikov’s rule all about and how does this impact regioselectivity in electrophilic addition reactions? As you follow along with my alkene reactions cheat sheet, you’ll notice that many reactions are labeled Mark or Anti-Mark and syn or […]
