Awesome, so easy to understand! There's just one thing I'm confused on: 12:00 where you mention an intramolecular methyl shift. I know previously that protons can move around a molecule so that it's more stable, etc.. but how does the methyl shift? I thought it is a bad leaving group. Is it floating in solution for a while before shifting? Is it "hard" or "unfavourable" to do such a methyl shift? Sorry, the idea was a bit unintuitive to me.. thanks Joe!
Hi, Ken! Thanks for watching and being a jOeCHEMist! In terms of carbocation shifts, yes you can certainly have hydride (aka "proton" even though you're technically moving H:- & not H+, so its a hydride shift, not a proton shift), BUT you can also move methyl groups in the event you're next door to a quaternary carbon. Methyl groups, although they're larger than hydride atoms, are "small enough" to move if it leads to a more stable result in terms of the carbocation. For a deeper explanation on carbocation shifts, see the video below! ruclips.net/video/hwQ8cFd3d88/видео.html
THANK YOU SO MUCH
