The difference between the two is determined by which atom the group added to (Mark vs Anti-Mark) or to which SIDE it adds (syn vs anti). When they add to opposite faces it’s considered anti addition. When both atoms/groups add to the same face it’s considered syn addition. Syn and anti addition refer to which face of the pi bond BOTH groups will add. Mark refers to Markovnikov’s Rule while Anti-Mark refers to anti-Markovnikov addition. The difference is explained below: Mark vs Anti-Mark What is Markovnikov’s rule all about and how does this impact regioselectivity in electrophilic addition reactions?Īs you follow along with my alkene reactions cheat sheet, you’ll notice that many reactions are labeled Mark or Anti-Mark and syn or anti. This is a critical pattern to both understand and recognize when studying alkene addition reactions. Markovnikov’s Rule tells us where to add the nucleophile and hydrogen in an asymmetrical alkene addition reaction.
