Halohydrogenation of alkenes

WebThe acid catalyzed hydration of alkene takes place as electrophilic addition reaction. The reaction involves the formation of carbocation intermediate. In reactions involving carbocation intermediates, the carbocation may sometimes rearrange if a more stable carbocation can be formed by the rearrangement. These involve hydride and methyl shifts.

WebOn the right is a di-substituted alkene. Now we have two alkyl groups and the di-substituted alkene is more stable than the mono-substituted alkene. To explain why, we need to go back to the idea of stability of carbocations that we saw in an earlier video. On the right we have a secondary carbocation. http://web.mit.edu/mollieb/Public/PDFs/Schoolwork/5.12-1.pdf
