Okay, so we're told that if we have a double bond and there is an ether substitute, we react this with hbr, that we typically see hydrogen added to one side and bromine added to the other.
00:18
That is, we see bromine added to the, i guess this is to be geminal position with respect to the ether, whereas we see hydrogen added bisinol.
00:37
Right.
00:38
So we see geminal addition of bromine.
00:41
That is, it's on the same carbon as the functional group we're talking about.
00:46
Okay.
00:46
Now the question is, why is this? right.
00:49
So let's draw this a little differently and start looking at a mechanism that could explain why this would be.
00:56
Right.
00:56
So we know that there's kind of two possibilities.
00:59
That's what they told us.
01:00
We know that the first step in addition of a hx over a double bond is that the double bond opens a up and grabs a proton, and then it can basically end up in one of two places...
