This question asked what the major product is from the addition of hbr to this molecule.
00:07
So i want to figure this out by drawing the mechanism.
00:11
So the first step that will happen in this reaction is that the double bond here, the pie bond, will come and grab the hydrogen, and we'll push the bromine off.
00:20
So then we'll get an intermediate that looks like this.
00:28
And then the hydrogen will go on the end here so we can put our carbocation in the middle, which is the more stable carbocatine option.
00:37
But this isn't the most stable that we can get, right? this is a secondary carbocadion.
00:42
We could make it secondary benzolic, though.
00:44
And so the way that we'll do that is by doing a hydride shift.
00:48
So we'll push this hydrogen over here onto this carbon...
