Hydride Shift and Methyl Shift Mechanism

Hydride shifts and methyl shifts can occur in organic chemistry reactions if there is a carbocation intermediate. While Markovnikov’s rule placed the carbocation on the more substituted of the 2 former sp2 (double bound) carbon atoms, if there is an EVEN MORE substituted carbon nearby you’ll get a carbocation rearrangement.

This video helps you understand the logic behind the carbocation rearrangement, along with specific patterns to look for when deciding between a hydride shift or methyl shift.

  1. Great video! thanks

  2. Hey Leah, wow. thank you! Is there anyway to see the steriochemistry for all of these reactions? If that’s part of the subscription how can I sign up? I don’t have use for the one on one tutoring because I kind of need the videos on demand. Much appreciated. I don’t understand why this isn’t the format professors use in class, it all makes sense now. Also, your voice is very soothing, panic has subsided :).

    • I don’t have a specific video on that, however I do cover stereochemistry of reactions in some of the study hall videos
