All right, so in this question, we're looking at whether or not these following carbocadions are going to rearrange.
00:06
So looking at a, you really can't rearrange this in such a way where it's going to form a more stable carbocadion.
00:16
Because i can either, if i want to do, like, for example, a one -two hydride shift, i'm either going to move it to either that location or that location.
00:24
And both of those would still be secondary carbocations, so the stability wouldn't greatly increase.
00:29
All right.
00:33
So talking about b, this is again a secondary carbocation, but we could do a 1 -2 -hydride shift.
00:40
And what that would do is shift to carbocadion to this position, being a tertiary carbocation, which is substantially more stable...
